Abstract:
A multimode resonator device comprising a single dielectric core having a substantial parallelepiped-shape and a supporting member having a lower dielectric constant than said dielectric core and which supports said dielectric core substantially in the center of a cavity having a substantial parallelepiped-shape, which produces a TM01&dgr;-x mode, a TM01&dgr;-y mode, a TE01&dgr;-x mode and a TE01&dgr;-y mode, and predetermined modes of the TM01&dgr;-x mode, the TM01&dgr;-y mode, the TE01&dgr;-x mode and the TE01&dgr;-y mode are coupled to each other by disturbing a symmetry of the dielectric core.
