The Application of the Supercondensed TLM Node to Propagation Problems in Inhomogeneous Anisotropic Materials

Abstract

A supercondensed TLM node for modelling inhomogeneous anisotropic media on an arbitrarily graded mesh without using stubs is developed. It requires less storage, computationally is more efficient and can operate on a higher time step then existing TLM nodes. Complete derivation, implementation and validation of the new node are presented in the paper.
