Abstract (in Japanese) (See Japanese page) 
(in English) A perturbation method using the TM<sub>010</sub> mode of cylindrical cavity is commonly used to measure the complex permittivity of a dielectric rod at microwave frequency. However, the method is limited to a low loss or thin cylindrical rod to assume the negligible change of the electromagnetic field inside the cavity after inserting a sample rod.
In this paper, a more accurate measurement method of complex permittivity of a dielectric rod is proposed to compensate the measurement values of the complex permittivity obtained from the conventional simple perturbation method by using compensation coefficients charts, which are calculated on the bases of the rigorous electromagnetic field analysis to take into account the effects of the sample insertion holes of cavity. The measurement results of a polyethylene rod verify this usefulness. The method, discussed in the working group of Japanese IEC/SC46F sub-technical committee, has been submitted to IEC as a committee draft (CD).
