Abstract
A multi-layer waveguide comprising at least three physical layers assembled into a multi-layer waveguide. The layers are a top layer, one or more intermediate layer, and a bottom layer. The multi-layer waveguide further comprises a waveguide channel being an elongated aperture in at least one intermediate layer. At least one layer has a metasurface on a first surface facing a first adjoining layer, wherein the metasurface surrounds the elongated aperture and comprise thick and thin sections.
