Study of Surface-Patch Techniques for Modeling Three-Dimensional Radiating or Scattering Objects.

Abstract

A theoretical study of the surface patch technique for solving for the electromagnetic fields of three-dimensional scattering and radiating geometries was conducted. Improved techniques for the numerical calculations were also developed. In particular, the Georgia Tech surface-patch algorithm was improved and tested for conducting prolate spheroids, circular and rectangular cylinders, and cubes. The numerical results were good even for the finite cylinders with sharp edges. The merits of the surface-patch for solving the general three-dimensional electromagnetic problems have thus been demonstrated. The development of a new surface-patch algorithm for solving thinshell problems is also discussed in this report. (Author)
