Abstract

The paper discusses quality factor of tunable shielded cylindrical metal-dielectric resonator taking into account dielectric losses. It was shown that dielectric loss decrease in case of the resonant frequency tuning with inclusion of the air gap between dielectric cylinder and metal plate. Calculations were performed using mode matching technique and finite integration technique. The results obtained with both methods are in good agreement. References 3, figures 2.
