Abstract
A resonance device includes a waveguide, a dielectric resonator disposed coaxial with the waveguide, an excitation structure thereof. One end of the waveguide is open and the other is short-circuited. The dielectric resonator has two end surfaces disposed on opposite sides to each other, is insulated from the waveguide in the vicinity of the open end of the waveguide, and is disposed within the waveguide, such that a thickness being a distance between the two end surfaces is constant, regardless of a radial position of the dielectric resonator. In a power transmission apparatus, the two resonance devices are provided. The open end of the waveguide of one resonance device and the open end of the waveguide of the other resonance device are disposed opposite each other. Power, which is input to an excitation structure of one resonance device, is output from an excitation structure of the other resonance device.
