Microwave applicator, exhaust gas purifier, heater, and chemical reactor

摘要

A microwave applicator includes a housing configured to contain an object of heating, multiple microwave resonators provided on and around a periphery of the housing, a microwave conductor interconnecting the microwave resonators, and a microwave generator configured to generate microwaves of different frequencies. Each microwave resonator is configured to resonate the generated microwaves of a resonant frequency of the microwave resonator, and to emit the resonated microwaves to the object of heating contained in the housing. Among the microwave resonators, a first microwave resonator and a second microwave resonator have respective resonant frequencies that are different from each other.
