Abstract :
The least-squares boundary residual method is used to develop an electromagnetic model for predicting the propagation characteristics and modal-field distributions of an elliptical waveguide loaded with a dielectric rod. Tests indicate that the model, when implemented as a selfcontained software package for running on the NEC SX-1A supercomputer, is capable of yielding numerical accuracies of better than +or-1%.
