Dielectric constant estimation device and dielectric constant estimation method

摘要

Problem to be solved: to provide a technique capable of easily estimating the dielectric constant of a sample in a short time and at a relatively low cost.The transmitter 1 transmits radio waves to the interior of the sample 10 having a three-dimensional shape.The plurality of receiving sections 2 are disposed at a position where the sample 10 is sandwiched between the receiving portion 2 and the transmitting section 1 to receive radio waves transmitted through the sample 10.The plurality of receiving portions 2 are arranged spaced apart from each other along the circumferential direction of the sample 10.The processing section 3 calculates the similarity between the measured data received by the plurality of receiving sections 2 and the calculated data obtained by assuming the dielectric constant of the sample 10 in the positional relationship between the transmitting section 1 and the receiving section 2 as in the case where the measurement data is obtained.Diagram
