摘要：

An analysis has been completed to provide guidelines for producing planar microwave resonators with 0-factors of the order of 10(6)-10(8) at a temperature of 4 K and a frequency of 1-20 GHz using high-T(c) superconducting thin films on sapphire shielded by suitable buffer layers. Buffer layers not only overcome the problems of film-substrate interactions and reduction of microcracks, but can also confine the field into the sapphire which enhances the Q(r) and Q(c) of the resonator.
