A permittivity estimation method for the rod-shaped dielectric by using scattering waves
Koya Suzuki, Takashi Komakine (Akita-NCT) EMD2015-10
Abstract (in Japanese) (See Japanese page) 
(in English) There are various methods for measuring the permittivity of the dielectric. In this study, we examined the permittivity estimation method for the rod-sharped sample without cutting by using a “scattered wave method” in spite of the size of the sample is limited far as sufficiently smaller than the wavelength for the method in which a radio wave is irradiated to the dielectric in the free space and the permittivity is estimated from the scattered wave intensity. The scattering wave power was measured for both the cylindrical sample and a rod-like one on which except for the exposure dimensions to be same as the cylinder the radio wave absorber shielded. Measured values of scattered wave power were -73.35 dBm for the cylindrical sample and -73.75 dBm for the rod-shaped sample, respectively, so that the observed power reduction for the rod-shaped sample should be due to the spread of polarization. The equivalent polarization correction value was obtained from the measured power ratio of cylinder and rod-shaped samples as 1.17. It becomes possible to estimate the relative permittivity of the rod-shaped sample by using this value.
