Abstract :
Split dielectric resonator (SDR) of H01δ type with a narrow slit located athwart to electric field is presented as: (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; and (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.
