Calculation of dielectric constant calibration characteristics of sensors using the method of moments

Анотація

This research is devoted to the issues of further development of methods of experimental measurement of dielectric characteristics of solid materials, liquids and liquid–gas media, which are foam structures. In recent decades, foam structures have gradually filled and supplanted traditional dielectric materials. There are still no scientific and metrology-based methods and devices for correct measurements of foam. In the paper, the method of moments (MoM) is employed for resonator measurements. The obtained results for a wide range of dielectric constants from 1 to 80 are interesting for determining the sensitivity of measurements, the influence of frequency measurement errors, and determining the number of measurement points.
