Scattering by Dielectric-Loaded Conductive Sectors: A Subdomain Method

초록

This letter studies electromagnetic scattering by dielectric-loaded conductive sectors using the subdomain method. The subdomain method decomposes two conductive sectors facing each other into two single-sector problems. This enables representing the scattered electromagnetic fields of their individual subdomains using Fourier–Bessel series in local coordinates. The boundary conditions are enforced by mode matching. Surface currents are compared with those obtained from the finite element method and both the convergence rate of modal coefficients and the relative root mean square error are examined. The results show that the proposed method produces accurate and computationally efficient solutions for the given problem. © 2002-2011 IEEE.
