Abstract : This document reviews the application of integral equation methods that are commonly used to study the interaction of EM fields with two- dimensional lossy anisotropic objects. The study focuses on plane wave scattering done by arbitrarily shaped cylindrical geometries that have circular and rectangular cross sections. In addition to discussing solid material objects, the document investigates the bistatic radar cross section of several metallic circular cylinders that are coated with a single layer of anisotropic material. The document concludes by investigating the radiation effects from a uniform line source that runs through a lossy anisotropic shell of finite thickness. The document discusses combined-field surface integral equations (CFSIEs). It presents highlights of the method of moments (MOM) numerical solution to CFSIEs and gives numerical results for solid, hollow, and coated cylindrical scatterers. The effects of material anisotrophy in the EM response of the scatterer are emphasized.
