A hybrid MTL/MoM approach for investigation of radiation problems in EMC

A hybrid approach is presented that combines the method of transmission lines (MTL) with the method of moments (MoM) to solve electromagnetic radiation problems on structures consisting of wires with complex terminations and three-dimensional conducting bodies. This approach is based on calculating the currents on wires using MTL and converting them to external sources for the remaining geometry to be handled by MoM. Validation of the MTL/MoM approach is done, its application to different wire, circuit and body configurations, including wire bunches, is illustrated, and its advantage over direct MoM calculations is shown.
