A modular junction topological approach to system interaction problems: simulation and validation

Abstract

This paper introduces a new topological scheme for electromagnetic compatibility simulation for aperture-system interactions. By introducing modular scattering junctions as wave propagation paths, this simulation method substitutes the multi-step computational process presented earlier by a single simulation step without ignoring backscattering interactions. The method also allows for modifications in the sub-structural level without simulating the entire system. The simulations involve transmission line matrix compaction, finite-difference timedomain method, and reciprocity theorem to create different junctions. The numerical results generated by this concept have been validated through experimental results and there is a good agreement between the simulated and experimental data.
