Abstract:
1. A microwave irradiation system comprising: first and second microwave generators, each comprising a microwave irradiating element and a microwave transmission part comprising at least one of a waveguide and a coaxial tube; an applicator comprising: a filter part through which at least one of the first and second microwave generators is connected to the applicator, wherein the filter part comprises metal blocks in the microwave transmission part of the at least one of the first and second microwave generators with a gap between the metal blocks across a predetermined length along the microwave transmission part; wherein the predetermined length is determined such that reflections of the microwaves from the at least one of the first and second microwave generators on the side of the filter part at an inlet and outlet of the gap are canceled out; and a filter, between the one end of the microwave transmission part of the applicator and the reflecting plane, is configured to transmit the microwaves from the at least one of the first and second microwave generators and reflect the microwaves with a polarization plane orthogonal to the microwaves from the at least one of the first and second microwave generators.
