Abstract : Under this grant the researchers have primarily investigated two classes of electromagnetic problems. The first contains the quantitative description of microwave heating of dispersive and conductive materials. Such problems arise, for example, when biological tissue are exposed, accidentally or purposefully, to microwave radiation. Other instances occur in ceramic processing, such as sintering and microwave assisted chemical vapor infiltration and other industrial drying processes, such as the curing of paints and concrete. The second class characterizes the scattering of microwaves by complex targets which possess two or more disperate length and/or time scales. Spatially complex scatters arise in a variety of applications, such as, large gratings and slowly changing guidance structures. The former are useful in developing microstrip energy couplers while the later can be used to model anatomical subsystems (e.g. the open guiding structure composed of two legs and the adjoining lower torso).
