A heterogeneous hybrid computational electromagnetics method is presented that permits conduction currents to cross the boundary between different computational domains. The method uses a standard frequency-domain moment-method program and the finite-difference time-domain method to compute the fields in the two regions. Several validation cases are examined and the results compared with available data.
