   Abstract:
   In this work, we utilize a our recently developed hybrid PSTD/FDTD method to simulate complex multiscale EMI/EMC problems. In particular, we use the PSTD (pseudospectral time-domain) method to model the regions with coarse structures (feature size larger than a wavelengths, where α ~ 1) since the PSTD method has spectral accuracy and is efficient in this regime. On the other hand, the alternating direction implicit conformal finite-difference time-domain (ADI-CFDTD) method is used to model fine structures (feature size smaller than β wavelengths, where β ≪ 1) to speed up the time integration. Finally, the conformal FDTD (CFDTD) method improved by the enlarged cell technique (ECT) is used for the intermediate scale. We demonstrate the significant saving in computer memory and computation time for several realistic EMI/EMC problems
