ABSTRACT:
An apparatus includes a first waveguide configured to focus an electromagnetic wave to a focal region, and a second waveguide defining an opening having an end positioned adjacent to the focal region, the second waveguide including a first metallic layer, and second and third layers positioned on opposite sides of the first metallic layer, wherein the first metallic layer has a first propagation constant larger than propagation constants of the second and third layers.
