A generic topological simulation scheme for studying aperture electromagnetic field interactions and cable couplings.

A modified electromagnetic topology (EMT) simulation scheme for the interactions of an electromagnetic wave with an aperture and with cables of an electrical system beyond the aperture is described. The modified EMT simulation scheme addresses a concept in dealing with an aperture node of the topological circuitry without having to specify the details of the entire electrical circuitry. The results of the modified EMT simulation scheme have been validated through experiments for aperture/wave interactions and the induced currents on the cable near the aperture. The aperture transfer functions, obtained for both the simulation and experimental cases, have shown the characteristic response similar to that of the high-pass filter with a cutoff frequency. The simulated and measured currents on a cable, placed behind the aperture, resulted in good agreement with each other, providing the good validation of the modified EMT simulation scheme. Under this scheme, any change in topological circuitry can be handled easily in the substructural levels without having to consider an entire system. Consequently, the effects of various types of aperture interactions on the entire system can be reinvestigated via simply remodeling of topological interaction nodes in substructural levels.
