摘要：

The microwave properties of single crystalline TiO2 (rutile) were investigated. At a frequency of 7.5 GHz the loss tangent tan delta was found to increase from 1.4X10(-7) at 4 K to 4X10(-6) at 70 K for electric fields parallel to the crystallographic a,b plane. The high permittivity of 105 and the small tans in combination with the low microwave losses of high temperature superconductors (HTS) were utilized to construct a miniaturized X-band resonator with a high quality factor Q. An assembly of two YBa2Cu3O7 films of 8 mm in diameter separated by a rutile cylinder of 2 mm height provides a TE(011) resonance at 9.7 GHz with Qs ranging from 6X10(5) at 10 K to 10(5) at 70 K. Frequency scaling of the losses in rutile and in the HTS films indicates Qs in excess of 10(6) at 1.8 GHz using YBa2Cu3O7 films of two inches in diameter. Such resonators are considered to be key elements for high-power filters in mobile communications. (C) 1995 American Institute of Physics.
