摘要： A multi-slot resonant microwave device comprises a plurality of slot microwave resonator units and at least one microwave emitting source. Each of the plurality of slot microwave resonator unit is defined as a slot resonant cavity. Whenever at least one of the microwave emitting sources emits microwave power into the plurality of slot microwave resonator units, the plurality of slot microwave resonator units resonate simultaneously, and produce an electromagnetic field with the same polarization direction. Therefore, the multi-slot resonator device can deal with large-area microwave heating with greater microwave effect to shorten operating time and accomplish the objective of homogeneous and megathermal microwave heating.
