Microwave Irradiation System

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 microwave transmission part connected to the first and second microwave transmission parts of the first and second microwave generators at one end thereof;
• a reflecting plane, at an other end of the microwave transmission part of the applicator, configured to reflect microwaves from the first and the second microwave generators to generate an electromagnetic mode at such a location that a space of an object to be irradiated, in the microwave transmission part of the applicator between the end and the other end is irradiated with both an electric field having a first electric field intensity and a magnetic field having a first magnetic field intensity generated by the first microwave generator and with both a magnetic field having a second magnetic intensity and an electric field having a second electric field intensity generated by the second microwave generator, wherein the first magnetic field intensity is greater than the second magnetic intensity and the first electric field intensity is smaller than the second electric field intensity;
• and
• a filter part through which at least one of the first and second microwave generators is connected to the applicator.
