提出并研究了Ka波段蓝宝石开槽介质谐振器（QDR）。谐振器在回音壁模式上被激发。利用圆概率误差对开槽圆盘谐振器进行了模式识别。测量数据与模拟的频率和谐振器的Q值进行了比较，测试和CEP下的铜样品。利用CST Microwave Studio软件进行了计算。提出和研究的蓝宝石QDR是一个有前途的基础，高精度测量小导电样品（非常规超导体，如pniktides和高温超导铜酸盐，纳米管等）。在毫米波长范围内。
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.
