Conductor modeling with the surface admittance operator of triangles

Abstract

This paper presents an accurate solution for the discretization of the Dirichlet-to-Neumann (DtN) operator in triangles. The resulting DtN matrix can be used for modeling conductors that are composed of triangles with a finite conductivity, and guarantees an accurate solution up to frequencies at which the skin effect is strongly present. The method is illustrated with some numerical examples.
