| Abstract(in English) | Precise designs and discussions are presented for sapphire rod resonators of three types, which have been proposed by the IEC/TC90/WG8 in the standard measurement method of the surface resistance R_s of high temperature superconducting (HTS) films; an open-type resonator, where a sapphire rod having diameter D and length L is placed between two parallel HTS films, a cavity-type resonator constructed by housing the open-type resonator in a copper circular cavity, and a closed-type resonator, where the sapphire rod is set in a cavity constructed from two HTS films and a copper ring having. diameter d and height h. Some mode charts for these three resonators are calculated from the rigorous analysis based on the mode matching method, taking account of an uniaxial-anisotropic characteristic of sapphire. Optimum dimensions for these three resonators are determined from the mode charts so as to separate the TB_<011> and TB_<013> modes used for measurements from the other modes. As a result, the closed-type sapphire resonators having the dimension ratio (D/L)^2=4 for TE_<011> mode resonator and (D/L) for TB_<013> mode resonator and the diameter ratio d/D=4 are proposed for the stable R_s measurement. |
