Abstract :
In this research, the relative dielectric constant for the liquid materials with no contact between a sensor and the materials are estimated. SE is first measured using a shield box. Then, the shield box with a multi-layered model is modeled with Sommerfeld integral, and the electromagnetic field is calculated at the observation point. Finally, the SE is calculated to be fitted to the measured value of SE, in order to estimate the electric parameters as an inverse problem
