Abstract

The present invention related to devices and methods that use returned power (RP) measurements during microwave energy delivery to perform one or more functions. For example, microwave devices and systems that comprise one or more features to measure the returned microwave power. One or more measurements of the returned microwave power may be used to obtain information about one or more of: antenna shape, system status and system performance. One or more measurements of the returned microwave power shaping elements may also be used to obtain information about one or more properties of the target material. The invention also discloses devices and methods for delivering microwave energy to a variety of target materials to achieve a variety of desired microwave effects.

Description

[0001] Cross-references to relevant application data [0002] This application claims priority to US Provisional Application Serial No. 61 / 686,125, filed March 31, 2012, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to apparatus and methods for using return power (RP) measurements to perform one or more functions during transmission of microwave energy. Background technique [0004] A typical microwave antenna designed to transmit microwave energy includes one or more metallic conductors electrically connected to a microwave generator by a transmission line. In use, the antenna acts as an impedance transformer between the microwave source and the medium to which the system transmits microwave energy. From the point of view of the circuit, the medium corresponds to the load in which the microwave energy from the microwave generator is finally stored. [0005] The impedance of the antenna is typically matche...
