Abstract: We present in this chapter a review of some recent research work about a new approach to the numerical simulation of time harmonic wave propagation in infinite periodic media including a local perturbation. The main difficulty lies in the reduction of the effective numerical computations to a bounded region enclosing the perturbation. Marcatili’s method is an approximate analytical method that describes how light propagates through rectangular dielectric optical was published by Enrique Marcatili in Optical dielectric waveguides guide electromagnetic waves in the optical spectrum (light). This type of waveguide consists of dielectric materials (e.g., glass, silicon, indium phosphide, etc). This volume includes articles on the mathematical modeling and numerical simulation of various wave phenomena. For many years Waves and its five prior conferences have been an important forum for discussions on wave propagation. The topic is equally important for fundamental sciences. We introduce continuous supersymmetric transformations to manipulate the modal content in systems of optical waveguides, providing a systematic method to design efficient and robust integrated devices such as tapered waveguides, single-waveguide mode filters, beam splitters and interferometers. These transformations connect superpartner profiles by smoothly modifying the transverse index.
