Abstract:
A circuit for coupling to electromagnetic waves for having current flow induced throughout the circuit, comprising:a substrate for supporting components of the circuit; and at least one switch comprising; (a) a first conductive element on said substrate for connection to a first component of said circuit, (b) a second conductive element on said substrate for connection to a second component of said circuit, and (c) a switch element made up of a switching material on said substrate, and connecting the first conductive element to the second conductive element, said switching material comprised of a compound which exhibits a bi-stable phase behavior, and switchable between a first impedance state value and a second impedance state value by application of energy thereto, affecting current flow between said first conductive element and said second conductive element resulting from a change in the impedance value of said compound.
