Full-wave analysis of metallic structures at optical frequencies
… effects are reviewed. Both the frequency-domain and time-domain methods for simulating the structures are discussed. The finite element method is applied to study the scattering from the metallic structures in the frequency domain. The simulation results are shown for two-dimensional …

Investigation of explicit finite-element time-domain methods and modeling of dispersive media and 3D high-speed circuits
In this dissertation, efficient time-domain domain decomposition algorithms are investigated, compared, and further enhanced, and a new domain decomposition method is proposed based on the knowledge of existing ones. First, several explicit domain decomposition methods, including the dual-field …

Modeling and design of near-field antennas with periodic structures
… in the design of near-field antennas. First, the discontinuous Galerkin time-domain (DGTD) method is applied to model the scattering from periodic structures. The modelling of dispersive media is incorporated into a three-dimensional DGTD scheme, which is capable of studying plasmonic periodic …
