Abstract

A rigorous approach to wave propagation in circularly bent planar waveguides is proposed. Open bent planar waveguide such as slab waveguide, H-guide and NRD waveguide are transformed into the bounded one by placing the concentric electric walls in radial direction. As the normal modes of the bounded bent waveguide are numerically obtained, it is possible to apply the standard modal matching approach to the analysis of the propagation along a bent waveguide connecting two straight waveguides. To verify the accuracy of the present method, numerical results for slab waveguide are shown and compared with the results by the conventional methods. Numerical results for circularly bent slab, H and NRD waveguides are shown.
