Генератор дифракционного излучения с асимметричной открытой резонансной системой. Часть 2. Результаты “горячих” исследований генератора дифракционного излучения

摘要

The hot test results of diffraction radiation oscillator with asymmetric open resonant system, in which the periodic structure was shifted to the field spot periphery of the operating TEM00q-mode, are presented. It is shown, that displacement of the periodic structure, in double grating form, to field spot periphery of TEM00q-mode allows extending the single-mode frequency tuning range and improves the overall efficiency of diffraction radiation oscillator. The mode competition features in diffraction radiation oscillator with double grating and asymmetric open resonant system are considered. The investigations were carried out in 8-mm waveband.
