title: Choice of boundary conditions for rectangular dielectric waveguides using approximate eigenfunctions separable in x and y.
abstract: In examining approximate eigenfunction solutions of a rectangular dielectric waveguide that are separable in x and y, we have found that a particular choice of field components of E and H for satisfying the boundary conditions results in orthogonal eigenfunctions for the different modes, while other choices do not.
