Abstract :
Accurate evaluation for MGF and its gradient is the key step in the MoM solution for scattering by BOR´s. We develop a new evaluation scheme for the singular MGF and its gradient. Compared with the scheme in (Glisson, 1978), our scheme employs more analytical solutions and removes the approximation in elliptical integrals. Also, the entire process is more rigorous and the results are suitable for higher-order calculation.
