Method of Moments Analysis of Scattering by Chiral Media

Abstract

In this report, the interaction of electromagnetic fields with objects composed of chiral media is analyzed using eigenfunction and method of moments techniques. The historical basis for the constitutive relationships of chiral media is presented in the first chapter. The wave equation, volume equivalence theorem, and image theory for chiral media are presented in the second chapter. An eigenfunction solution for scattering by a multilayer circular chiral cylinder with a center cylinder described by an impedance surface is developed in the third chapter. A pulse-basis point-matching method of moments solution for scattering by an inhomogeneous object composed of chiral media in free-space or in the presence of a perfectly conducting half-plane is presented in the fourth chapter. A spectral-domain Galerkin method of moments solution for a microstrip transmission line on a chiral substrate is developed in the fifth chapter. Numerical data in each case demonstrated that the chirality of the objects causes a significant asymmetry in the electromagnetic fields, which is not present for achiral objects.
