Experimental Study Of Ohmic Effects In Open Coaxial Cavities

Abstract

A study of selective properties of coaxial open cylindrical resonators has been conducted experimentally and compared with theory. Mode discrimination is achieved both by exploring selective ohmic effects and examining the electrodynamic properties of the coaxial cylindrical waveguide. The effectiveness of a lossy silicon carbide coaxial insert in providing effective radial mode selection is demonstrated in that the total Q factors of TE,, modes with radial index p 2 2 become well below the quality factors for surface TE,1 modes.
