Abstract :
The coupling properties of coupled dielectric waveguides were evaluated by using a novel and powerful method, the GIE (generalized integral equation) method, which relies on the concept of equivalent planar polarization dipole moments to simulate the guides. Generalized impedance boundary conditions are enforced to provide a simple planar integral equation. This method can account for multiple dielectric strips on different levels. Phase constants of the different modes and coupling characteristics were calculated for several structures, such as rib waveguides and insulated image guides.<>
