Mode coupling due to a magnetized plasma in a cavity: FDTD simulation

Summary form only given, as follows. Experiment and theory have shown that a significant amount of radiation is produced at a much higher frequency than that predicted by the upshifting of a single mode in a cavity containing time-varying and space-varying plasma. Mendonca (1996) used WKB method to examine the mode coupling due to the spatial variation of the plasma density in the cavity. We have recently developed a three dimensional finite-difference time-domain algorithm to simulate a time-varying and space-varying magnetized plasma and examined the mode coupling in a cavity. The evaluation points in space of the electric field E, the magnetic field B, and the current density field J are shown.
