Operating Electrically Small Antennas for High Information Bandwidths

Guest Lecturer: Prof. Ramakrishna Janaswamy, University of Massachusetts, Amherst

Location: MITRE (Building C Lobby)

Refreshments served at 2:30pm

It is well known that electrically small (size to be much smaller than the wavelength at the operating carrier frequency), passive antennas suffer from fundamental limitations on achievable bandwidths. The bandwidth of electrically small antennas could, however, be substantially improved by incorporating lossy matching networks. But this will be at the cost of significantly higher power dissipation in the matching networks, which will tend to decrease the overall radiation efficiency. If, on the other hand, the antenna currents could somehow be made to change rapidly at a rate directly dictated by the message signal, then there is no difficulty in radiating such a rapidly varying waveform from the induced antenna currents, despite its narrow input impedance bandwidth.

In this talk we discuss the theory of operation of a linear, electrically small, time-varying antenna by considering a thin dipole loaded with a fast switching element. Time-variation of antenna structure is achieved by operating the switch via a message signal that has the overall effect of transferring a modulated carrier to antenna currents for subsequent radiation.

Time-domain integral equation and linear state-space theory is used to understand the dynamics of the radiated waveform and the antenna input current. It is demonstrated that the antenna has capabilities of radiating waveforms with an information bandwidth that is an order of magnitude greater than possible with an electrically small traditional antenna. Effect of switch parameters such as the finite OFF resistance and finite switching times relative to the time period of the RF carrier on the operation of the antenna are also presented.

Deer Island Wastewater Treatment Plant: Basic Process Overview and Major Project Initiatives

Richard J. Adams, Deputy Director, Engineering Services, Deer Island Treatment Plant

The Deer Island Treatment Plant (DITP) provides wholesale and wastewater services to over 2.5 million customers in 61 communities in Massachusetts. DITP is the second largest treatment plant in North America. The plant has been in full operation for over 15 years. During this time, major equipment and infrastructure enhancements have taken place mainly due to energy efficiency initiatives, equipment life cycles and technology. The MWRA has experienced a number of unforeseen problems, ranging from corrosion due to the proximity of the marine and H2S environment that has necessitated a large portion of the infrastructure/equipment upgrades. In addition, the MWRA has also implemented a number of energy efficiency project ranging from hydro, wind and solar projects to recapturing waste heat recovery systems that has resulted in generating additional electricity that has significantly lowered its requirement to purchase power from the local utility. This discussion will provide an overview of the original construction; provide a basic understanding of how the wastewater treatment plant operates and to discuss past success and failure of infrastructure and equipment replacements.

Richard Adams received his B.S. in Electrical Engineering from Northeastern University in 1987. He has been involved in the oversight of engineering and construction for on Deer Island for the past 19 years. Currently he is involved in oversight of a $650 million Capital Improvement program. Prior to this, he worked developing design and overseeing construction for electric utility and major manufacturing facilities.

For the previous 7 years, he has been managing the Engineering and Capital program for DITP. Through this period, he has been responsible for the oversight of over $250 million of design and construction projects ranging from Primary/Secondary Clarifiers rehabilitation, installation of 700 KW of solar arrays, installation of a 1.2 MW back pressure steam turbine (heat recovery), 1.2 MW of wind turbines and the installation of a central SCADA system to monitor and control 43 medium voltage electrical substations for Deer Island.

Before working for the MWRA, Mr. Adams worked for a local electric utility located in Westborough, MA and managed a number of distribution systems and energy efficiency programs for the utility.

Anthropogenic Global Warming – Yea or Nay.

Paul H. Carr, Ph.D., AF Research Laboratory Emeritus

Thaddeus Paul Kochanski, Ph.D., (Ted) Sensors Signals Systems

Join the Life Members and the Electron Devices Society in debating: Anthropogenic Global Warming {“APG”} – Yea or Nay. We begin with two opening statements by the two advocates: Paul H. Carr: -- Yea – “Humans Influence Our Climate”; Thaddeus Paul Kochanski – Nay –“Natural Processes Dominate Climate Dynamics“

Humans Influence Our Climate
By Paul H. Carr, IEEE Life Fellow

Fossil fuel burning and agriculture of the exponentially growing population of seven billion are affecting our climate. Fossil fuel emissions include carbon dioxide (CO2) and aerosols. Fossil fuel mining and rice and livestock farming produce methane (CH4).

Increasing CO2 and other noncondensing atmospheric gases like CH4 blanket and warm the earth’s surface via the greenhouse effect. These increases correlate with temperature since the beginning of the industrial era. Carbon dating shows that the CO2 increase is from burning ancient fossil fuels.

The present CO2 rate-increase of 2.5 ppm/year is 300 times greater than that at which the earth recovered from the ice age 18,000 to 10,000 years ago.

If we do not take steps to reduce the 2.5 ppm/year rate, in 240 years CO2 concentrations will reach 1000 ppm. This is what the earth’s atmosphere was 50 million years ago. Then there was no ice, sea levels were hundreds of feet higher, and average temperatures were 11C higher.

The 2014 report of the UN Intergovernmental Panel on Climate Change concluded, “There is a 95 percent or greater likelihood that human activity is the main cause of the ongoing planetary warming.”

Natural Processes Dominate Climate Dynamics:

Are Climate Data & Models Reliable?
By Ted Kochanski

Before we can get to the ultimate question – we need to address:

My interest began, in the 1980's, while investigating atmospheric effects on low altitude RF propagation for the Navy. I experienced several instances of quality and reliability issues with archived ocean surface water and air temperature data in NOAA's National Climatic Data Center.

In June 1990, I attended a debate at MIT on Global Warming, between Pro -- Dr. Stephen Schneider of the National Center for Atmospheric Research in Boulder, Colorado, and Anti -- Richard S. Lindzen, MIT Sloan Professor of Meteorology. Afterwards, Prof. Lindzen, an atmospheric dynamics and modeling expert, told me that he accepted the surface temperature data. Being an experimentalist, I gave the modelers a “by” on the physics – my problem was with the data. Subsequently, I’ve seen many more examples of problems with: data sources, their interpretation, and modeling [e.g. cloud formation].

The remainder of the meeting will be devoted to members of the audience asking their own questions to further elucidate the topic.

Ted Kochanski, SB MIT, Ph.D. U Texas at Austin, Dr. Kochanski is a consultant, educator, and entrepreneur with a background in experimental physics, and extensive expertise in developing, and utilizing multiple sensor technologies to characterize, monitor and control diverse physical systems. His professional career spans: Tokamaks (University of Texas at Austin); Chair Technical Review Panel on Alpha Particle Diagnostics for Fusion Experiments; Defense System Analysis (MIT Lincoln Laboratory); Sensors Signals Systems – wide range of domestic and international clients in technology, applications, intellectual property; Entrepreneurship (co-founder of several high-tech companies); Engineering Education: university (UNH, WIT, International); continuing education (IEEE Boston Section); informal education (Museum of Science Exhibit Hall Interpretation Volunteer for 20 years).

Prof. Nian X. Sun, Professor of Electrical and Computer Engineering at Northeastern University, Boston.
Phone: +1 (617) 373-3351 Email:

The coexistence of electric polarization and magnetization in multiferroic materials provides great opportunities for realizing magnetoelectric coupling, including electric field control of magnetism, or vice versa, through a strain mediated magnetoelectric interaction effect in layered magnetic/ferroelectric multiferroic heterostructures [1-7]. Strong magnetoelectric coupling has been the enabling factor for different multiferroic devices, which however has been elusive, particularly at RF/microwave frequencies. In this presentation, I will cover the most recent progress on novel Nian Sun Photolayered microwave multiferroic heterostructures and devices, which exhibit strong magnetoelectric coupling. We will demonstrate strong magnetoelectric coupling in novel microwave multiferroic heterostructures. These multiferroic heterostructures exhibit a giant voltage tunable magnetic field of 3500 Oe, and a high electrostatically tunable ferromagnetic resonance frequency range between 1.75~ 7.57 GHz, a tunable frequency of 5.82 GHz or fmax/fmin=4.3 [2,3]. At the same time, we will demonstrate E-field modulation of anisotropic magnetoresistance, giant magnetoresistance and exchange bias at room temperature in different multiferroic heterostructures [4]. New multiferroic devices will also be covered in the talk, including ultra-sensitive nanoelectromechanical systems magnetoelectric sensors with picoTesla sensitivity [5], multiferroic voltage tunable bandpass filters [6], voltage tunable inductors [7], tunable bandstop filters, tunable phase shifters and spintronics, etc.

Introduction To Antennas: Antennas For EMC


Dr. Vince Rodriguez from ETS-Lindgren, Distinguished Lecturers of the EMC Society

In this presentation, the speaker does a quick review of antenna concepts and parameters. The presentation is oriented towards engineers that never took an antenna class all the way to those that took one many years ago. Dr. Rodriguez uses numerical simulations to help the audience visualize the difficult concepts and parameters related to antennas engineering. The presentation goes over the concept of antenna, the mechanisms of radiation followed by the radiation patterns and all the different parameters that describe the radiation pattern. After an introduction of the basics concepts Dr. Rodriguez provides a survey of the most typical antennas used in EMC testing. After the presentation the audience should be able to get a better understanding of antennas and antenna parameters.

Vince Rodriguez attended The University of Mississippi (Ole Miss), in Oxford, Mississippi, where he obtained his B.S.E.E. in 1994. Following graduation Dr. Rodriguez joined the department of Electrical Engineering at Ole Miss as a research assistant. During that time he earned his M.S. and Ph.D. (both degrees on Engineering Science with emphasis in Electromagnetics) in 1996 and 1999 respectively. After a short period as visiting professor at the Department of Electrical Engineering at Texas A&M University-Kingsville, Dr. Rodriguez joined EMC Test Systems (now ETS-Lindgren) as an RF and Electromagnetics engineer in June 2000. During this time he was involved in E field generator design and the RF design of several anechoic chambers, including rectangular and taper antenna pattern measurement chambers some of them operating from 100MHz to 40GHz. He was also the principal RF engineer for the anechoic chamber at the Brazilian Institute for Space Research (INPE) the largest chamber in Latin America and the only fully automotive, EMC and Satellite testing chamber. In September 2004 Dr. Rodriguez took over the position of Senior Principal Antenna Design Engineer, placing him in charge of the development of new antennas for different applications and on improving the existing antenna line. Since the fall of 2010 he has served and Antenna Product Manager. In this position Dr. Rodriguez oversees all technical and marketing aspects of the antenna products at ETS-Lindgren. Among the antennas developed by Dr. Rodriguez there are: broadband double and quad-ridged guide horns; high field generator horns; stacked LPDAs for automotive and military testing; and printed antennas for wireless testing. While mainly dedicated to antenna design Dr. Rodriguez has continued being involved in anechoic chamber design like the Conical Taper L-shaped range at the national University of Singapore.

Dr. Rodriguez is the author of more than fifty publications including journal and conference papers as well as book chapters. Dr. Rodriguez holds patents for hybrid absorber and for a dual ridge horn antenna. Dr. Rodriguez is a Senior Member of the IEEE and several of its technical societies. He is also a Senior Member of the Antenna Measurements Techniques Association (AMTA), as well as, a member of the board of directors of AMTA where he has served as meeting coordinator (2010-2011) and as vice president for the year 2012.
