Influence of Electrical Properties of Dielectric Sample to Electromagnetic Field Distribution Inside Solenoid-Type Dielectric Sensor

Abstract-Traditional dielectric sensors such as parallel-plate or coaxial cylindrical metal electrodes have some limitations and disadvantages, including the corrosion of electrode, the occurrence of electrode polarization, the reaction of the sensor material with dielectric samples, etc. This paper aims to investigate the influence of electrical properties of dielectric samples to the behaviors of electromagnetic field distribution inside solenoid-type dielectric sensors and the relationship between the electrical sensor parameters to be measured and material properties of dielectric samples considered, using numerical electromagnetic field analysis method. According to the numerical electromagnetic field analysis, it can be concluded that (i) In the case of high-resistivity dielectric samples such as insulating liquids and powders, the distribution capacitance is more preferable in identifying the dielectric properties of sample to the change of Q-quality; (ii) In the case of high-conductivity dielectric samples such as water and other aqueous solutions, the change of Q-quality is much more sensitive to that of the dielectric properties of sample to the distribution capacitance.
