Moment-method calculations of scattering by a square plate using singular basis functions and multipole expansions

Andersson, Tommy LU (1993) In Journal Electromagnetic Waves and Applications 7(1). p.93-121
Abstract
The method of moments is used to solve electromagenetic boundary value problems numerically. It is known that the choice of basis functions is crucial for the numerical efficiency. Fast convergence is achieved provided the basis functions efficiently approximate the unknown function. In this paper the far field (incl. RCS) of a thin square conducting plate is calculated. Basis functions with correct edge and corner singularities are shown to greatly enhance the convergence compared to ordinary "rooftop" functions. The calculations of the matrix elements as well as the right side of the matrix equation and the scattered field are simplified by the use of a multipole technique.
