摘要：

An automated open resonator system is designed and constructed for precision measurement of the loss tangent and dielectric permittivity of low absorbing materials at 60 GHz. The use of a high-Q hemispherical Fabry-Perot cavity together with highly stabilized synthesized phase locked Gunn oscillator sources and a superheterodyne receiver enabled us to measure loss tangent value as low as 10-mu-rad. Both cavity length variation and frequency variation techniques were utilized to provide precise data.
