Abstract :
The propagation characteristics of coupled rectangular dielectric waveguides are analyzed using the electric field integral equation. In contrast with the widely used subdomain basis Galerkin´s method, in this work a novel set of entire-domain basis functions is utilized. This set consists of plane wave functions that satisfy Maxwell´s equations in each guiding region. Computed dispersion curves are presented for a mm-wave transmission line and compare very closely to results of other techniques. The present implementation can also deal with integrated optical circuits and its main advantage is superior numerical efficiency.<>
