A model of plasma frequency probes utilizing plasma fluid equations and finite difference time domain (FDTD) theory.

摘要

As man continues to search the unknown, additional tools are needed to develop and analyze new probes. This thesis will present a full wave Finite Difference Time Domain model that is capable of analyzing radio frequency probes immersed in realistic ionospheric plasma. The five moment approximations, Maxwell's equations and the plasma fluid equations, are discretized using a finite difference time domain method. Balmain's and Adachi theories are used to validate the simulation at the gyro and hybrid resonance points. Finally, with the model developed, the simulation is used to analyze a microstrip patch plasma impedance probe immersed in hot collisional magnetized plasma.
