INVESTIGATION OF A CLASS OF ELECTROMAGNETIC BOUNDARY VALUE PROBLEMS.

Abstract

The purpose of this project was to apply a class of newly developed techniques to the solution of problems involving waveguide discontinuities, scattering, and diffraction as well as inverse scattering problems. Another objective of the project was to study image processing and inverse scattering techniques involving coherent fields. A rather large number of waveguide as well as open-region boundary value problems has been investigated using the modified residue calculus technique and extended versions of the same. The relative advantages of these methods over conventional numerical methods have been demonstrated. Investigation of the inverse scattering problem between parallel planes has been completed. The inverse scattering approach has been extended to solve the problem of scattering from cylinders of arbitrary cross section. (Author)
