High-Q dielectric resonator with operated slit (Tunability, Thermal Stability, Film Measurements)

Split dielectric resonator (SDR) of H type with a narrow slit located athwart to electric field is presented as: 01δ (1) electro-mechanically tunable DR utilizing fast piezo-actuator; (2) high-Q resonant system with thermal self-stabilization of its resonant frequency using thermal expansion for compensation; (3) measurement device to study dielectric film parameters, including their temperature characteristics. Proposed SDR theoretical analysis based on the combination of partial regions methods and collocations, shows agreement with experimental results
