Abstract
The usefulness of the Fabry-Perot resonator as a sample cell in microwave spectrometer-type gaseous pollution detectors is discussed. The design of a new 70-GHz semiconfocal resonator with variable microwave coupling and wide-range piezoelectric tuning is presented. Experimental data were taken on cavity tuning performance and on the behavior of the variable microwave coupling structure. Theoretically obtained value for the cavity Q-factor is compared with experimental data.Keywords
