Building Trefftz Finite Elements for Electromagnetic Problems

Abstract

Generalized algorithm to build descriptor matrices of convex politope. Trefftz finite elements is introduced in the paper. A finite number of plane waves is used to expand electromagnetic field inside the elements. Projections of the intra-element field on an additional set of basis functions defined on the element surface are used to build admittance matrix descriptors of the element.
