| Abstract: | A cavity porturbation method is analysed for determination of complexpermittivity of microwave single crystal dielectric materials. The some exporiments are madewith the TE_(10m) mode rectangular cavity and an automatic scalar network analysing system atLN_2 and room temperature; The results prove that the technique covers measurement of gener- al microwave dielectric materials at different temperature (ex.LN_2, LHe_2 and room tempera-ture). The test is simple, rapid and automatic, and some directional complex permittivity of dielectric materials can be measured. |
