Abstract Details

2015, Doctor of Philosophy, Ohio State University, Electrical and Computer Engineering.
This work investigates various numerical methods for modeling and analyzing microwave components and electronic devices with multi-scale structures and multi-physics effects. In the first part of the work, a universal matrice approach is developed that can handle continuous changing material properties across the element and curved boundary. This method is implemented in an Interior Penalty based domain decomposition solver. Several interesting numerical examples including the modeling of the Luneburg lens and conformal perfectly matched layer validate this method. In the second part, a full-wave homogenization process of extracting the equivalent permeability tensor of ferromagnetic nanowire array is presented. By solving for the small signal model of the Landau-Lifshits equation, the macroscopic material property can be obtained for the heterogeneous structure. After that, the utilization of ferromagnetic nanowire array into microwave components and devices is studied, showing interesting properties such as double-band working frequencies and self-bias capability. Coming to the third part of this dissertation, time domain method for transient linear/non-linear effects in high-frequency circuit systems is explored. To be specific, a discontinuous Galerkin time-domain method integrated with SPICE circuit solver and IBIS models, respectively, is developed. The key technique is on the interface the coupling of EM solver and circuit solver. This work provides a self-consistent integration so to physically model the whole system. Since the coupling process is local for DG method, only modest resources are needed. Overall, this dissertation evaluates and develops several numerical methods with the determination to provide a platform for multi-scale and multi-physics simulations for EM analysis of modern radio frequency systems with linear/nonlinear and passive/active factors.
