Abstract
A dielectric resonator comprising a resonant defect structure disposed in a lattice structure formed of a plurality of multi-dimensional periodically arranged dielectric elements confines electromagnetic energy within a frequency band in the photonic band gap. The frequency band of the confined electromagnetic energy is tunable. The unique structure of the dielectric resonator leads to reduced power dissipation losses when used in microwave and millimeter wave components. Accordingly, the dielectric resonator PAC BACKGROUND This invention was made with government support under Contract Number N00014-86-K-0158 awarded by the Department of the Navy and Contract Number DAAL-03-86-K-0002 awarded by the Department of the Army. The government has certain rights in the invention.
