Computation of radiated and scattered field using separate frequency domain moment-method regions and frequency domain MOM-FDTD hybrid methods

An approach to hybridisation of the method of moments and the finite difference time domain method is investigated. This hybrid method is capable of analysing a system of multiple physically-unconnected regions by employing the principle of equivalent sources. The case of multiple sources in the presence of scattering objects is discussed. Some examples are given for testing the validity of the approach and results are compared with other available data.
