Method of moments solution to scattering from a rough

Question

Method of Moments

The method of moments solution to scattering from a rough surface for a TM wave begins with the integral solution to the wave equation

Eⁱ = kη₀/4∫_s Js(ρ')H₀⁽²⁾(k|ρ-ρ'|)dS'

In matrix form this can be rewritten as

where

and e = 2.718... and γ7 = 1.781 .... By inverting A, the source current, J₈ can be solved for, from which the scattered electric fields can be calculated.
