Abstract :
A finite-difference time domain (FDTD) method is developed for the analysis of the electromagnetic wave propagation in semiconductor waveguides containing a magnetostatic-field controlled plasma. Dispersion characteristic curves are obtained for a variety of waveguides. However, since the FDTD formulation developed cannot excite evanescent modes for a sufficiently long time, only the dynamic or propagating modes are excited. As a result, the desired non-reciprocal effects, associated with these modes could not be examined.
