Abstract

In this article, a new formula for computing the impedance matrix in the moment method is presented. By use of the properties of the basis functions, Green function, and the Fourier transformation, the integrals of the impedance matrix element can be simplified into one double integral (for two dimension) and one triple integral (for three dimension) when using the Galerkin's method. The singular point in the integrals can easily be removed through a suitable variable transform. The impedance matrix for the two dimensional case are computed by use of two kind of basis (One is the product of two triangular functions. Another is the roof-top function). Three examples of scattering from conducting plates are presented.
