    Summary

    My group's research spans two interdisciplinary areas in electrical engineering: the development and application of time-domain computational electromagnetics (CEM) techniques with an emphasis on photonics and bioelectromagnetics, and the development of microwave diagnostic and therapeutic technologies for biological and medical applications.

    In the last twenty years, we have witnessed enormous progress in the field of time-domain CEM. The predictive capability of today's state-of-the-art finite-difference time-domain (FDTD) methods of solving Maxwell's equations has proven invaluable in the innovation of numerous emerging technologies. One such example is the field of microphotonics where optical devices are being miniaturized to the mesoscopic scale and integrated in a manner analogous to microelectronics. Another example is the field of bio-photonics. Our research in CEM has also focused on the development of fundamental advances in FDTD algorithms to extend their applicability to several important classes of electromagnetics problems that have not been previously amenable to such analysis. Examples include problems in bioelectromagnetics and nonlinear optics in which the physics of electromagnetic wave interactions with materials must be incorporated into the numerical model. These research activities are conducted primarily in the UW Computational Electromagnetics Laboratory (3415 Engineering Hall).

    Our research activities also include a significant theoretical and experimental program in the field of bioelectromagnetics, emphasizing microwave diagnostic and therapeutic technologies for biological and medical applications. Current activities are focused on the development of a novel ultrawideband (UWB) space-time microwave imaging approach for detecting early-stage breast cancer, as well as UWB microwave hyperthermia techniques for breast cancer treatment. We are also conducting dielectric spectroscopy measurements of excised breast tissue specimens to understand the biophysical mechanisms responsible for the observed dielectric properties of normal, benign, and malignant breast tissue. These multi-disciplinary research efforts involve faculty and students in ECE, BME, and several departments in the Medical School. In another project, we are investigating non-thermal subcellular responses of biological cells to wideband and narrowband radiofrequency radiation. All of this work is conducted in the UW Laboratory for Medical Applications of Microwaves (3559 Engineering Hall) as well as at the University of Wisconsin Hospital and Clinics.
