摘要：
A quasi-optical resonator is implemented to characterize low loss polymer powders at mm waves. Based on the suggested resonator configuration, density-independent moisture measurements have been carried out in W-band. The resonant frequencies and Q factor were measured to reconstruct the real and imaginary parts of a dielectric constant to be used for moisture determination. The model needed to describe this quasi-optical resonator including the reconstructing algorithm has also been developed. An example illustrating the method proposed is reported.
