Abstract

New and simple analytical methods for propagation constants of a high permittivity rectangular dielectric waveguide are presented. At first, we determine an infinite number of candidates for eigenvalue pair (k_x,k_y) by eigenvalue equation derived from main electromagnetic fields of the mode. Next, we select a correct eigenvalue pair by minimizing a discontinuity of secondary components on the boundaries. Our numerical results show a good agreement with that of previous numerical methods even for high permittivity
