Transmission-line modeling method - TLM

We have presented the TLM method as it applies to solving electrical problems of some complexity. The basic techniques have been presented in some detail. Emphasis was placed in dealing with complexity by describing embedding techniques whereby advantage is taken of local solutions in the vicinity of complex objects to interface these solutions with surrounding fields obtained from the TLM method. This approach permits a largely uniform and structured mesh throughout the problem space thus enhancing efficiency and at the same time dealing with problematic features through the embedding of special nodes. This appears to be the optimum approach, however, each problem has its own characteristics and modelers must…
