Patent ID: 8248075

Claim:
A system for dissipating a standing wave, comprising: a microwave energy source configured to intermittently delivery microwave energy as a periodic microwave signal; an energy delivery network configured to transmit the periodic microwave signal, the energy delivery network including: a microwave energy delivery device; a network analyzer; a first resistive load; and a transfer switch connected between the microwave energy source, the microwave energy delivery device, the first resistive load and the network analyzer; wherein the first resistive load is connected between the transfer switch and a ground potential, and wherein the transfer switch in a first condition connects the network analyzer to the microwave energy delivery device and the microwave energy source to the first resistive load and the transfer switch in a second condition connects the microwave energy source to the microwave energy delivery device and the network analyzer to the first resistive load; and a circuit connected between the microwave energy source and the energy delivery network, wherein the circuit is configured to pass the periodic microwave signal from the microwave energy source to the energy delivery network when the periodic microwave signal is present and to dissipate standing waves when the periodic microwave signal is absent.
