Abstract

We propose an improved macromodel-based technique for efficient analysis of EBG structures in the finite difference time domain (FDTD) scheme. The technique involves macromodel symmetrization and diagonalization as well as cloning hundreds or even thousands of macromodels along the FDTD grid. The improved FDTD-macromodel scheme allows one to use macromodels on a large scale within the computation grid. Numerical results show that a high resolution analysis of EBG structures can be performed in time comparable to the coarse mesh FDTD simulation
