Abstract

A simple moment solution is given for the problem of electromagnetic scattering from two dimensional structures consisting of multiple perfectly conducting and lossy dielectric cylinders of arbitrary cross-section. The system is excited by a plane wave polarized transverse electric to the axis of the cylinders. The equivalence principle is used to replace the cylinders by equivalent electric and magnetic surface currents radiating into an unbounded medium. Two different sets of coupled integral equations involving the surface currents are obtained by enforcing the boundary conditions on the tangential components of the total electric and magnetic fields. The method of moments is used to solve the integral equations. Pulses are used for both expansion and testing functions. Some of the limitations of the method are briefly discussed. Results for the surface currents and the scattering cross sections are presented. Results computed using the E- field and/or the H- field formulation are in very good agreement with the exact or other available published data.
