Abstract : This report consists of a summary of accomplishments over the past three years. Only a brief resume of the topics covered is presented; detailed descriptions are contained in reports and publications which are referenced in context with these resumes. The investigations are concerned with the guiding, scattering and radiating properties of a variety of structures, particularly those with periodic properties. The wave types have been primarily electromagnetic, although a later phase has included acoustic waves as well. The studies themselves are basic in character, with emphasis on thorough treatments; the motivation for the topics chosen has in all cases been their importance and usefulness in various applications. Among the topics treated in detail are: leaky waves and surface waves, Cerenkov radiation, Smith-Purcell radiation, effects of glide and screw symmetry in periodic structures, radiation from corrugated surfaces, Wood's anomalies in scattering theory, Bragg scattering from acoustically-modulated regions, and parametric interactions in nonlinear optics and acoustically-modulated media, including the effects of boundaries.
