On the Implementaion of the Equivalence Theorem in the Hybrid FDTD-MoMTD TechniqueAbstract
The hybrid FDTD-MoMTD technique is a powerful tool for analysing the transient excitation of inhomogeneous permeable bodies by arbitrary thin-wire antennas. The technique is based upon the calculation of the equivalent electric and magnetic currents on a Huygen's surface that encloses the antenna. The paper studies, by means of several numerical experiments, the effects on the accuracy of the results of the size of the Huygen's box, the size of the spatial increment in the FDTD algorithm and the distance from the Huygen's surface to the observation point.
