Electromagnetic radiation and scattering from a system of conducting bodies interconnected by wires

The problem of electromagnetic radiation and scattering from a perfectly conducting system of arbitrarily shaped bodies interconnected by wires is considered. The method of moments is used to solve the electric field integral equation. The bodies are modeled by triangular patches and the wires by a series of straightwire segments. A special vector expansion function is introduced at each of the junction regions. This function is simpler and gives better results than the ones used by previous investigators. The procedure is applicable to both open and closed surfaces. Results are in the form of input impedances, near fields and field patterns. A general-purpose user-oriented computer code is available. Its application domain is quite broad, extending from computer systems composed of several boxes interconnected by coaxial cables to a wide variety of antennas mounted on arbitrarily shaped bodies. There is no theoretical limit to the number of apertures on surfaces of the bodies.
