Webb1 jan. 2014 · Since a dielectric resonator can be thought of as a truncated dielectric rod waveguide, this research was essential for scientific understanding of electromagnetic phenomena in dielectric resonators. In 1939, Robert D. Richtmyer published a study [ 5 ] in which he showed that dielectric structures can act just as metallic cavity resonators. Webb("r) or less, where 0 is the free space wavelength, and "r is the material dielectric-constant. The radiation Q-factor and frequency of resonance can be altered by the aspect ratio of the DRA for a ﬁxed value of "r. With the absence of surface waves, the conductor losses are minimum in DRA and high radiation efﬁciency can be achieved [11]. http://www1.isti.cnr.it/~salerno/Microonde/DielectricResonators.pdf bob hitchcock belper
