| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To estimate the dielectric permittivity in high frequency, a method measuring the field strength of scattered waves re-radiated from the dielectric sample placed in a applied well-known field was proposed. This method can easily estimate the dielectric permittivity without contact in small sample size compared to the wavelength. The permittivity of the pure water which radiates the relatively larger scattered waves is estimated in order to certify the measurement principle. The sample is enclosed by spherical rubber in diameter of 80 mm and the scattered field is discriminated from applied field by absorbers arranged between transmitting and receiving antennas. For the samples which have the relatively small dielectric permittivity, the scheme which modulates the strength of scattered waves by mechanical vibrations to discriminate the scattered field superposed with the applied electric field and the coherent approach in receiving process, is introduced. In this case, the calibration technique using the calibrator whose volume, shape and dielectric permittivity are well-known is available practically. At the field frequency, 1 GHz, the dielectric permittivity of spherical Teflon of 20-mm diameter can be estimated with the error of 2 percents when the measuring system is calibrated by the Alumina calibrator of the same diameter. | |
