Summary

My research interests cover a broad range of problems involving electromagnetic fields and waves. Generally, topics of interest to me are related to some aspect of new sources and/or applications of high frequency (i.e., radio frequency to microwave to x-ray) electromagnetic radiation. Specific examples of recent research problems are outlined below.

New advances in communications, radar, solid state spectroscopy, remote sensing, fusion energy research, and materials processing require the development of tunable, wideband, high-power sources of coherent electromagnetic radiation in the microwave, millimeter, submillimeter, and higher frequency regimes. Solid state sources do not, and will not, satisfy all of the needs of such applications, as many require higher total efficiency and powers in much smaller packages than a solid-state-based device can provide. These needs require high-tech vacuum devices which employ electron beams. Our research in this area enables improved devices with higher power, higher frequency, more compact size, greater efficiency, better linearity, new abilities to linearly amplify multiple signals simultaneously, etc.

Currently, for example, my research interests are focused on increasing the power and/or frequency of high power vacuum electron sources of microwaves, millimeter-waves, and terahertz-regime radiation. One challenge is to find new cathodes, capable of emitting high current densities with reduced heating, or even operating at room temperature (via field emission). Another challenge is to understand the fundamental physics of ohmic dissipation in conducting surfaces at millimeter-wave and terahertz-regime frequencies (100 - 3000 GHz). This knowledge will provide guidance on the required surface conditions to minimize this source of radiation loss in waveguides and cavities. I also continue to have interest in the development of miniature sources of millimeter-wave and THz regime radiation (30 GHz - 3 THz) using microfabricated vacuum electron devices.

Many of my current interests in electromagnetic fields research emphasize biological or biomedical applications -- i.e., bioelectromagnetics. For example, in collaboration with Professor Hagness and many others we recently completed the first comprehensive and definitive study on the microwave dielectric properties of human breast tissue, both healthy and cancerous. This data will be used to develop improved methods for breast cancer detection and treatment protocols based on microwave imaging and heating. In another project, we are investigating how to optimize and exploit the phenomenon of electroporation where pores form in the membranes of cells when exposed to short pulses of intense electric fields. The insights of this research are applicable to cancer and other tissue disease treatments, as well as, we believe, to possible strategies for tissue engineering and regeneration.

"You and Your Research"--by Richard Hamming: Transcription of the Bell Communications Research Colloquium Seminar delivered by Richard Hamming on 7 March 1986. This seminar is excellent for stimulating you to think intentionally about how you choose to invest your time, both professionally and personally. The overall message is to make sure that what you do is important. It has advice for all level of employees, including management. Warning: Hamming�s specific recommendations, in some cases, represent an extreme view of how to manage the balance of work and life. I do not personally share his value that technical work should trump everything, including your personal relationships or extracurricular activities. For most of us, following his model in all aspects will amount to running your life like a sprint, not a multi-decade-long marathon, and burn-out is a likely result. But whatever you do, do it intentionally, and invest it with meaning and purpose, including your work, and you should reap maximum satisifaction. Nevertheless, reading this seminar should stimulate you to think more deeply about your life plans, both professionally and personally, and that is the intention.
