The authors present a new hybrid technique for analysing complex electromagnetic problems, combining a marching on in time version of the MoM and the FDTD. The use of the equivalence principle allows the problem to be separated into two simpler problems, and a proper set of equivalent sources is defined to account for the coupling between actual sources and scatterers.
