Abstract

Integration of the method of moments (MoM) and the finite-difference time-domain method (FDTD) into the iterative multi-region (IMR) technique is presented in this paper. This hybrid method combines the desirable features of MoM and FDTD to solve large scale antenna and scattering problems more efficiently. The idea of this hybrid method based on the IMR technique is to divide an original problem domain into unconnected subregions and use the more appropriate method in each subregion. A time waveform construction algorithm is presented to enable integration of MoM solutions at multiple frequencies with FDTD solutions.
