Source-Type Integral Equation Analysis of Circularly Curved Channel Waveguides ina Multi-Layered Background

摘要

In previous publications, integral equation methods have proven to be a powerfulmodeling tool for both straight and circularly curved waveguides. These methods are fully vectorial and mathematically rigorous. In a previous publication the source-type integral equation method has been successfully applied to circularly curved channel waveguides in an homogeneous embedding. In the present paper the method is extended to curved channel waveguides embedded in a multi-layered background. These are the type of structures that are usually encountered in integrated-optical and opto-electronic devices. (Copyright (c) 1994 Laboratory of Electromagnetic Research.)
