ANALYSIS OF RESISTANCE AND INTERNAL REACTANCE IN SYSTEMS OF PARALLEL CONDUCTORS

A general coupled surface integral equation formulation and a numerica l solution procedure have been employed for the analysis of systems of multiple parallel conductors of general cross sections over a relativ ely wide frequency range. The conductors are excited by a transverse m agnetic (TMz) plane wave. Results for resistance and internal reactanc e for systems of multiple circular and rectangular conductors have bee n obtained, and the proximity effect has also been studied for multico nductor systems by comparing the cases of different spacings between c onductors. The proximity effect causes both the resistance and the int ernal reactance of the outer conductors to increase and causes the res istance and internal reactance of the inner conductors to decrease at moderately high frequencies.
