MEASURING THE PERMITTIVITY OF DIELECTRIC MATERIALS USING STDR APPROACH

Abstract

This paper presents a new approach for measuring dielectric properties of materials.The proposed approach is based on applying the synthetic time domain reflectometry to a dielectric filled waveguide.The compromising measurement results show that this algorithm can be successfully applied for measuring other parameters of the materials.Also, the approach has been successfully applied to detect the discontinuities of as a multi-section microstrip line.This approach is very useful in measuring the electromagnetic parameters of the different liquids, gels, and solid materials.
