“…The highest azimuthal order modes, i.e., whispering gallery (WG) waves, have the highest -quality factor. The devices are quasioptical, so DR's with two conducting endplates (CEP) and WG waves are, as a matter of fact, the quasioptical (QDR) Hakki-Coleman resonators [6]. They have acceptable dimensions in mm waverange and are promising for using in resonant structures with HTS films.…”

Abstract-We have developed a surface resistance ( ) measurement technique for large-area high-temperature superconducting (HTS) films using quasioptical dielectric resonators (QDR) with HTS endplates (quasioptical Hakki-Coleman resonators). In this technique, the highest modes, namely whispering-gallery modes, in sapphire disk sandwiched between HTS films or between one HTS film and one Cu endplate are excited at K-band frequencies. The authors report on measurement results of surface resistance of 52 mm diameter high-quality YBCO thin films. The measurement results revealed that the technique is feasible for accurate -measurements of large-area thin films. The method is appropriate for standard measurement of at millimeter wave frequencies by analogy with classic DR-based microwave technique, although QDR-based technique has some fundamental differences.
