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

Abstract

A theoretical study of the surface patch technique for solving 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, and cubes. The numerical results were good even for the finite cylinders with sharp edges. An Electric Field Integral Equation algorithm was also developed and tested satisfactorily on thin plate scattering problems. The merits of the triangular surface-patch for solving the general three-dimensional electromagnetic problems have thus been demonstrated. (Author)
