Abstract:
1. A multi-layer apparatus comprising: a first conducting layer including an input port, wherein the input port is configured to transmit millimeter electromagnetic waves; a second conducting layer including at least one through-hole; a first layer between the first conducting layer and the second conducting layer, wherein the first layer includes a first waveguide including a through-hole of greater width than the at least one through hole of the second conducting layer, and wherein the through-hole of the first waveguide is aligned at least in part with the input port and the at least one through-hole of the second conducting layer; a third conducting layer including an output port, wherein the output port is configured to receive millimeter electromagnetic waves; and a second layer between the second conducting layer and the third conducting layer, wherein the second layer includes a second waveguide including a through-hole of greater width than the at least one through hole of the second conducting layer, wherein the through-hole of the second waveguide is aligned at least in part with the output port and the at least one through-hole of the second conducting layer, and wherein the at least one through-hole of the second conducting layer is configured to couple millimeter electromagnetic waves from the first waveguide to the second waveguide.
