SCATTERING BY A TILTED STRIP BURIED IN A LOSSY HALF-SPACE AT OBLIQUE INCIDENCE

By M. Lucido

Full Article PDF (1,842 KB)

Abstract:
The analysis of the scattering by a tilted perfectly conducting strip buried in a lossy half-space at oblique incidence is formulated as an electric field integral equation (EFIE) in the spectral domain and discretized by means of Galerkin's method with Chebyshev polynomials basis functions weighted with the edge behaviour of the surface current density on the strip. In this way, a convergence of exponential type is achieved. Moreover, a new analytical technique is introduced to rapidly evaluate the slowly converging integrals of the scattering matrix coefficients consisting of algebraic manipulations and a suitable integration procedure in the complex plane.
