Calculations of photonic band structures, optical interactions at nonideal surfaces, and studies of linear and nonlinear surface excitations.
I earned my B.S. degree from Stanford University in 1953 and my Ph.D. from the University of Bristol (England) in 1957. After four years at the University of Maryland, College Park, as a postdoctoral fellow and assistant research professor, and five years at the Westinghouse Research Laboratories, I joined the UCI Physics Department in 1965.
A large part of the research activity in my group is devoted to the theoretical study of surface phenomena.
A primary area of interest is the scattering of electromagnetic waves from randomly rough surfaces. Of particular interest are effects due to the coherent interference of each multiply-scattered optical path and its reciprocal partner. These include enhanced backscattering, enhanced transmission, satellite peaks, new angular intensity correlation functions, and changes in the spectrum of polychromatic light due to rough surface scattering. Most of the existing calculations of these effects by computer simulations have been carried out for one-dimensional random surfaces. Efforts are currently underway to extend such calculations to two-dimensional surfaces. Another aspect of rough surface scattering that is being actively pursued is the design of one- and two-dimensional randomly rough surfaces that scatter or transmit light with a specified angular or spatial dependence of the intensity of the scattered or transmitted light, or that produce scattered or transmitted light with specified coherence properties.
As a teacher, I believe that my role is not only to transmit information to my students but also to teach them how to think, and to reason. The latter is more difficult, both for the teacher and for the student, than the former, but ultimately more rewarding, since the knowledge a student receives will change with time, particularly in a rapidly evolving field such a physics, but the ability to reason transcends such changes.
