Abstract

A surface integral equation is derived for electromagnetic scattering by highly conducting permeable objects of irregular shapes and solved, numerically, using the method of moments. The analysis make uses of the impedance boundary condition to simplify the formulation and reduce the computation time and memory requirements associated with the method of moments. Results for the induced voltage across a receiving loop antenna are presented. The computed and exact theoretical results for spherical objects are in good agreement.
