Claim:
1. A power transmission apparatus comprising: a first resonance device including a first waveguide, a first dielectric resonator disposed coaxial with the first waveguide, and a first excitation structure for exciting the first dielectric resonator; and a second resonance device including a second waveguide, a second dielectric resonator disposed coaxial with the second waveguide, and a second excitation structure for exciting the second dielectric resonator, the first waveguide having an open end as one end and a short-circuited end as the other end, the first dielectric resonator having two first end surfaces disposed on opposite sides to each other, being insulated from the first waveguide in the vicinity of the open end of the first waveguide, and being disposed within the first waveguide, such that a thickness being a distance between the two first end surfaces is constant, regardless of a radial position of the first dielectric resonator, the second waveguide having an open end as one end and a short-circuited end as the other end, the second dielectric resonator having two first end surfaces disposed on opposite sides to each other, being insulated from the second waveguide in the vicinity of the open end of the second waveguide, and being disposed within the second waveguide, such that a thickness being a distance between the two second end surfaces is constant, regardless of a radial position of the second dielectric resonator, and the first resonance device and the second resonance device being disposed such that the open end of the first waveguide and the open end of the second waveguide are opposite to each other, and power input to the first excitation structure being output from the second excitation structure.
