ABSTRACT:
A circuit for guiding electromagnetic waves includes a substrate for supporting components of the circuit. The circuit includes a control device which includes a first conductive element on the substrate for connection to a first component of the circuit and a second conductive element on the substrate for connection to a second component. The control device is made up of a variable impedance switching material on the substrate which exhibits a bi-stable phase behavior. The compound has a variable impedance between a first impedance state value and a second impedance state value which can be varied by application of energy thereto to thereby affect the amplitude or phase delay of electromagnetic waves through the circuit.
