Matched absorbing medium techniques for full-wave TLM simulation of microwave and millimeter-wave components

摘要

This paper investigates the absorbing layer tech- niques for three-dimensional transmission-line matrix (3D-TLM) simulations. Applications are the full-wave analysis of structures such as microwave and millime- ter-wave circuits open to free space. Two approaches are presented. Namely the matched layer(ML) and the perfectly matched layer(PML) technique which is used for general cases. For the ML technique, which is effi- cient for matching guides operating in a quasi-TEM condition, a comparison of the different TLM condensed node is carried out.
