Surface-wave waveguides

We present simulations and measurements of surface-wave waveguides (SWGs) for guiding surface waves (SWs) along straight and curved paths. In its simplest form, the SWG is a two-dimensional analog to a dielectric waveguide where a low-index material surrounds a high-index material. The most common m...

Description
Summary:We present simulations and measurements of surface-wave waveguides (SWGs) for guiding surface waves (SWs) along straight and curved paths. In its simplest form, the SWG is a two-dimensional analog to a dielectric waveguide where a low-index material surrounds a high-index material. The most common method for realizing materials with differing SW index is to use a grid of metallic patches of varying size on a dielectric substrate. The phase front of the guided SW can be precisely controlled using a combination of SW-index grading and rotation of the SW-index tensor.
