Abstract
A comparison has been made between cavity and open-resonator measurements of permittivity ϵ' and dielectric loss angle δ at 35 GHz. Two comparisons were made, the first using one set of samples of unsintered polytetrafluoroethylene measured in both systems and the second using two sets of similar samples, one set measured in each system, of a high density polyethylene (Rigidex 2000), cut from the same rod. The measured values of ϵ' and δ obtained by the two systems agreed within the limits of the experimental errors. The standard deviations obtained for ϵ' and δ were 0.0021 and 2.1 μrad, respectively. A discussion of the uncertainties associated with each measured parameter is given.Keywords
