Abstract (in Japanese) (See Japanese page) 
(in English) Equivalent circuits of thirteen fruit and vegetable samples were deduced from S-parameters measured at frequencies 1 - 100 MHz using a portable VNA and a tiny SMA probe. Admittance values calculated from the S-parameters were plotted on the admittance-Smith chart, and the equivalent circuits were synthesized by curve-fitting. The admittance in the lower frequency range was mainly determined by two large capacitive and two small resistive elements related to the plant cell wall and membrane. The measured and calculated admittance curves were in good agreement. Thirty five samples were classified as fruit and vegetables according to four criteria deduced from the RF analysis.
