Development and Testing of a Gallium Electromagnetic (GEM) Thruster
"An ablative, quasi-steady electromagnetic plasma accelerator is tested to quantify various characteristics of its operation. An array of diagnostics are used to characterize a gallium plasma produced by an arc discharge with current levels in the range of 5.6 - 22.6 kA. Discharge current and arc …

Numerical analysis of radio-frequency sheath-plasma interactions in the ion cyclotron range of frequencies
Electromagnetic plasma waves in the ion cyclotron range of frequencies (ICRF) are routinely used in magnetic fusion experiments to heat plasmas and drive currents. However, many experiments have revealed that wave energy losses in the plasma edge and at the wall are significant, and detected that …

Interaction elementary excitations in ultrarelativistic plasmas: damping mechanisms and plasma thermodynamics
… of the elementary excitations in quark-gluon and electromagnetic plasmas. Due to Debye screening and Landau damping mechanisms, the interaction fields fall off at large distances, except for static magnetic and color-magnetic fields. The lack of screening of the magnetic interaction leads to a …

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 …
