| Abstract(in English) | A measurement method using the TM_<0m0> mode cylindrical cavity with a dielectric rod sample inserted on the center axis has been proposed to measure the complex permittivity (the relative permittivity ε_r and the loss tangent tanδ), where accurate values of ε_r and tanδ can be obtained by the rigorous electromagnetic field analysis on the basis of the Ritz-Galerkin method. In this paper, based on this method, frequency dependence of complex permittivity of a polyethylene rod sample was measured using the TM_<010> and TM_<020> modes for four cavities with different sizes. These measured results were compared with ones for the conventional perturbation method. As a result, for the ε_r measurements, the scattered error by the present method was improved to 2.0 percents against 4.5 percents for the perturbation method. On the other hand, for the tanδ measurements, the measured results by these methods agreed within the scattered error 10 percents. |
