A Modular Junction Topological Approach to Aperture - System Interaction Problem

A new approach to perform electromagnetic topology based simulation is proposed by incorporating a modular scattering junction concept. This method substitutes the multistep computation technique presented earlier and is convenient to implement. The method also allows for incorporating substructural modifications without repeating solutions to the entire system. The simulation of the overall interaction utilizes transmission-line matrix compaction, finite-difference time-domain method, and reciprocity theorem to create different junctions. Results are compared with experiments conducted in the laboratory. A good agreement is shown for the simulated and experimental data.
