Abstract
A coupler for coupling electromagnetic radiation into a cavity, including a metal layer having a reflective surface and forming a ground plane; and one or more waveguides for gigahertz or terahertz electromagnetic radiation embedded in the metal layer. The waveguides each include two openings in the metal layer exposing a dielectric underneath; and a section of the metal layer between the two openings. A plurality of holes in the metal layer are disposed along a perimeter of the openings so as to shape the electric field of the electromagnetic radiation in a cavity coupled to the coupler.
