Quasi-optical dielectric resonator (QDR) in a form of slotted sapphire disk sandwiched between conducting endplates (CEP) is proposed and studied in Ka-band. The resonator is excited on whispering gallery modes. Mode identification of the slotted disk resonator with CEP is carried out. The measurement data are compared with simulated frequencies and Q-factors of the resonator with a copper sample under test and CEP. The calculation results are obtained using CST Microwave Studio software. The proposed and studied sapphire QDR is a promising basis for high accuracy measurements of small conducting samples (unconventional superconductors e.g. pniktides and HTS cuprates, nanotubes etc.) in millimeter wavelength range.

Abstract

The resonator is excited on whispering gallery modes. Mode identification of the slotted disk resonator with CEP is carried out. The measurement data are compared with simulated frequencies and Q-factors of the resonator with a copper sample under test and CEP. The calculation results are obtained using CST Microwave Studio software. The proposed and studied sapphire QDR is a promising basis for high accuracy measurements of small conducting samples (unconventional superconductors e.g. pniktides and HTS cuprates, nanotubes etc.) in millimeter wavelength range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
