Abstract:
Example multi-layer apparatus for electromagnetic waves and methods for fabricating such apparatus are described. An example apparatus may include a first conducting layer including an input port and a second conducting layer including at least one through-hole. The apparatus may also include a first layer between the first conducting layer and the second conducting layer, including a first waveguide aligned at least in part with the input port and the at least one through-hole. The apparatus may also include a third conducting layer including an output port. The apparatus may also include a second layer between the second conducting layer and the third conducting layer, including a second waveguide aligned at least in part with the output port and the at least one through-hole. The at least one through-hole may be configured to couple millimeter electromagnetic waves from the first waveguide to the second waveguide.
