Abstract
"A hybrid technique combining frequency and time domain methods is proposed to accurately and efficiently model the energy coupling in complex electronic systems. With a hybrid technique, each sub-circuit of a complex system can be analyzed by the mostproper numerical method so that the computational effort can be significantly decreased. Whereas large-scale regions will be characterized by a Haar-based Multiresolution Time-Domain (MRTD) scheme, sub-circuits containing a lot of details are modeled withthe Method of Moments (MoM), Finite Element (FEM) or Finite Difference Time-Domain (FDTD) technique. Huygens surface currents are applied on the boundary surfaces of the sub-geometries to interface the frequency and time-domain methods. In addition to theMoM method, an analytical approach is proposed to model penetrable conductive shields in FDTD or MRTD efficiently. Furthermore, for highly nonlinear sub-circuits, an extended FDTD method will be available and will be combined with the MRTD method. Finally,the computational efficiency of the hybrid method will be demonstrated by a comparison of the accuracy and computation time with a brute-force full-wave method. The outcome of this project will benefit electronic system designers in both the military andindustry by letting them accurately characterize the electromagnetic coupling effects among the various sub-circuits."
