Nonlinear Polymer Nanocomposite for Field Grading in Medium-Voltage Power Converters under High-Altitude and Humid Environments
… the development and characterization of a nonlinear resistive polymer nanocomposite (PNC) coating designed to enhance insulation within medium-voltage (MV) power modules and suppress flashover on printed-circuit boards (PCBs) at high altitudes. Electric field simulations of the triple-point …

Frequency and time domain analysis of carbon nanotubes with realistic shape and distribution
… of the junction, leading in some cases to a nonlinear conductivity. The electromagnetic scattering characteristics of these nonlinear CNT structures need to be quantified to predict their response to incident electromagnetic radiation. Time-domain electromagnetic codes facilitate the analysis …

Nonlinear terahertz spectroscopy of electronic and vibrational responses in condensed matter systems
… high-field terahertz (THz) pulses to initiate nonlinear responses in several classes of materials. We have developed several methods for interrogating the nonlinear THz response of materials including collinear and noncollinear THz-pump/THz-probe spectroscopy, and THz-pump/optical probe …

Computational modeling and simulation of nonlinear electromagnetic and multiphysics problems
In this dissertation, nonlinear electromagnetic and multiphysics problems are modeled and simulated using various three-dimensional full-wave methods in the time domain. The problems under consideration fall into two categories. One is nonlinear electromagnetic problems with the nonlinearity …
