Scattering Matrix Descriptors of Trefftz Finite Elements

Abstract

This paper explains some details related with the choice of the surface or mortar basis functions for the Trefftz finite elements. It is shown that appropriate normalization of the surface basis functions lead to unambiguous definition of the generalized admittance matrix descriptor of the element and to a possibility to define scattering matrix descriptor of the element. A brick element is investigated to illustrate the approach.
