Radiation from multiconductor transmission lines: Exact time-domain analysis

An exact expression for the radiated EM fields due to a multiconductor transmission line structure with a wire or ground plane as a return path has been presented. First the coupled equations describing the system have been decomposed to find the current along the lines, and then a time-domain approach has been presented to derive the radiated fields. It has been shown that the radiated field can be expressed as a function of the voltages and currents in the terminals.
