Abstract

Propagation of radiation field excited on a step-like discontinuity of dielectric slab waveguide is considered by using two different techniques: the Finite-Difference Beam Propagation Method and the Green´s Function Method. Comparison of these techniques enables to evaluate approximations used in the FD-BPM as well as the truncation errors and influence of interface conditions.
