抄録

We present a possible suggestion method to measure a permittivity of material without cutting a sample by means of the rectangular cavity resonator. A theoretical discussion on the possibility is given in this paper by studying the relationship between the material permittivity and a resonance frequency of the electromagnetic field inside cavity which is calculated by the FDTD method. We show the permittivity measurement chart by which the permittivity can be estimated from the measured resonant frequency. The permittivity estimated has a reasonable agreement with an empirical value within an error of several percents. The present result supports the validity of the present method.
