Precise Measurement of Low Loss Dielectric Materials Using Quasi-optical cavity Technique
The method of Fabry-Perot quasi-optical cavity isone of the most accurate methods for the precisionmeasurements of complex permittivity and loss tangent of lowloss dielectric materials at millimeter wave frequencies.In ourearlier work,a fixed operation frequency is employed for thecavity length variation technique.In recent years,with theincreasingly high-precision request and the instrumentationprogress in both hardware and software,the frequencyvariation technique has become commonly used inquasi-optical cavity system.In this paper,we describe someconsiderations in quasi-optical resonator test systemdesignation,together with mode identity techniques and themeasurement results of some materials.
