Abstract
We analyze the rectangular dielectric waveguide for millimeter wave and integrated optics applications using a combination of numerical and analytical methods. The problem is solved numerically in one dimension, while in the other dimension it is treated with propagators, reflection operators and mode matching. We derive an equation for the propagation constant of the waveguide which can be solved efficiently. The method is demonstrated to be numerically efficient, and with a good choice of grid distribution it can give a good value of the propagation constant even near to cutoff. We also derive the field plots of the guided modes, and suggest a method for mode classification.
