Entire-domain basis functions from group C/sub 2v/ in MoM for 2D EM scattering problems

In this paper, a novel class of entire-domain basis functions for the method of moment (MoM) for electromagnetic scattering from scatterers whose cross section is symmetric about both x and y axis is presented. The basis functions are constructed using group theory. Point-matching method with the above basis functions has been applied to solve the electromagnetic scattering of an egg-like scatterer. Accurate numerical result is obtained with much less memory in much shorter time.
