Application of the weighted residual method for one and two dimensional wave propagation problems
Abstract
In this paper the Weighted Residual Method (WRM) is introduced to solve one- and two-dimensional wave propagation problems. The basic principle of the WRM is described briefly and two practical examples are analyzed in detail involving wave propagation in an inhomogeneous medium with arbitrarily varying permittivity and permeability and a parallel-plate waveguide aperture illuminating a homogeneous slab terminated by a metal sheet. A complete comparison of the different weighted residual approximations in CPU time, rate of convergence, and error associated with numerical results is made.
