Monofrequency excitation of half-open resonator

Abstract

The trend for the realization of millimeter wave oscillation systems with a single resonance response in a wide frequency region follows from the many possible applications such as a spectroscopy, radio measurement, and mm wave generation. The using of additional dispersive elements in an open resonator is a dominant way of spectrum rarefaction. The open resonator as an oscillation system for mm wave generator has a number of good points. Investigations of the so-called half-open resonator (HOR) with Gunn diodes and support elements have been carried out. This resonator type appears to have considerable promise for one-diode oscillators and combiners as well as for microwave integrated circuits. This report is devoted to the study the spectral characteristics of a HOR, utilising a diffraction grating, for high Q single mode oscillating systems.
