Abstract
In this paper the origin of nonphysical solutions obtained with Galerk in's method is described. To remove these spurious solutions a practic al criterion is derived. It is shown on a patch resonator example with expansion functions satisfying edge conditions, that spurious solutio ns generated by the conventional approach are eliminated by the applic ation of the proposed method.
