Abstract

See full text

According to a microwave frequency setting device, an additional signal source outputs an additional signal. An adder adds the additional signal to a microwave to output the microwave thus-obtained. A reflected signal measurement section measures a power of a reflected signal that is produced by reflection of an output from the adder having entered a microwave furnace, the microwave furnace being adapted to accommodate therein an object to be processed with the microwave. A local minimum frequency measurement section measures a local minimum frequency, the local minimum frequency being a frequency at which a measurement result provided by the reflected signal measurement section has a local minimum. A frequency setting section sets a frequency of the microwave to the local minimum frequency measured by the local minimum frequency measurement section. A frequency band of the additional signal includes a resonance frequency of the microwave furnace.
