Extended PML-TLM node: An efficient approach for full-wave analysis of open structures. (English) Zbl 0978.78008

Summary: This paper deals with an extension and improvement of the PML-TLM algorithm first proposed by Dubard and Pompei. The approach is first extended to advanced nodes (hybrid SCN and super-SCN). Then its efficiency in the presence of evanescent waves is improved. As a result, stability is also improved. Finally, the algorithm is applied to the characterization of a new class of patch antennas and validated by the measurement.
