High-Quality Corrugated Resonators for Measurements at Millimeter and Submillimeter-Wave Bands

Abstract

The general-purpose set of resonator for the band 32-405 GHz has been studied both theoretically and experimentally. The described resonators are cylindrical cavities with corrugated side surfaces and flat end covers. The simple theoretical approach for TM 0mn eigenmode analysis is given. Physical principles of Q-factor enhancement, mode selection, frequency stabilization, and matching with standard waveguides are discussed. Experimental techniques and measurement data are given. The loaded Q-factor of (0.6-1.0) × 10 5 at VSWR (voltage standing-wave ratio) < 2.0 has been achieved together with high mode selection and high-frequency stability. A wide range of applications is proposed.

“…Amongst wide-range high quality resonator best feature in centimetre range lengths of the waves possess designed by us cylindrical many mode wide-range resonators [1][2][3], but in millimeter and submillimeter range -opened quasi optical resonators with rarefied by spectrum of the own modes, as well as new type of the resonator -corrugated [4,5]. The kit high quality wide-range resonators within the range of frequencies from 06 before 260 GHZ is submitted for drawing l.The designed resonators are characterized by importance's own …”
