| Abstract(in English) | In this paper, a method for measuring a complex permittivity of a powder sample is proposed based on the standing wave method on a rectangular waveguide for measuring a complex permittivity in microwave band. The complex permittivity of the powder sample, e.g., polyethylene powder and silica powder, was measured by inserting the sample box made of the teflon filled with the powder sample into the waveguide. The influence of the air existed between the particles of the powders was removed by the corrective equation derived from Mossotti-Clausius' equation, and then only the complex permittivity was estimated. The effectiveness of the present method of measurement was confirmed by comparing the powder sample with the measured result of the solidificated sample. In the case of the real part of the complex permittivity, there was a difference in the first decimal place. The estimation of the imaginary part was also carried out under the accuracy with the difference appeared in the second decimal place. It was shown that the effectiveness of our present method for measuring the complex permittivity of the powder. |
