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.
