Abstract:
1. A microwave-sending device for emitting microwaves, comprising: electronics for generating microwaves; a wave coupler; a waveguide; and a wave-emitting section, wherein said wave coupler couples the microwaves generated by said electronics to said waveguide, wherein at least the electronics, the wave coupler, and the waveguide are affixed to one another by being embedded within a common cast part, wherein said cast part and said waveguide are formed of materials having different relative permittivities and relative permeabilities, wherein said cast part and said waveguide adjoin each other so as to form a boundary layer at a junction thereof due to said different relative permittivities and relative permeabilities, wherein said boundary layer being able to guide said microwaves between said cast part and said waveguide, and wherein the cast part completely encloses the electronics, the wave coupler, and the waveguide except for a wave emitting section which is exposed.
