A simple numerical method based on generalized telegraphist’s equations as a full vector-wave analysis tool for dielectric waveguide problems is presented. The method is applied to various guiding structures for single-mode and multimode computation. The generalized telegraphist’s equation formulates the problem as a matrix eigenvalue equation whose solution spectrum of eigenvalues directly gives the modal propagation constants. Accuracies of better than 0.08% are possible for calculating the propagation constants.
