Complex Relative Permittivity Measurement Techniques

Abstract

This article presents a review of the techniques for measuring complex relative permittivity and also explains basic properties for understanding the principle of complex relative permittivity measurement. There are 6 measurement techniques mentioned in this article. These techniques consist of open-ended transmission line techniques, waveguide and coaxial transmission line techniques, free space transmission techniques, planar transmission line techniques, resonator method and resonant-perturbation method. In addition, the advantages, disadvantages and applications of these measurement techniques are discussed.
