This work describes and evaluates a technique for determining the dielectric properties of carbon-black filled Ethylene Vinyl Acetate (EVA) rubber and presents results on the studies of the effect of frequency on the permittivity and microwave conductivity using resonant cavity perturbation method. The measurements are performed with the aid of a Network Analyzer in X-band. The simplicity of this method lies in the fact that the dielectric properties can be obtained directly from the analytical formula without taking recourse to calibration.

Journal of Microwave Power and Electromagnetic Energy

A technique has been designed to determine the relative permittivity and dielectric loss of low loss materials using a cylindrical cavity resonator at X band. This technique has been tested over some standard materials with satisfactory results compared to some existing standard methods for measuring tanδ. The measurements are performed TE111 mode with the aid of Agilent E4418B EPM series power meter and Agilent 53150A 20 GHz frequency counter. © 2014 Taylor and Francis Group LLC.

A novel technique to measure small dielectric losses using cylindrical cavity resonator at X band

The cavity perturbation method is widely used in the study of electromagnetic properties of dielectric materials at X-band frequencies. It works well for the measurement of low-loss and medium loss materials. In this paper an easy and reliable method is discussed for the accurate determination of the dielectric constant of medium loss samples such as Teflon and Perspex. ©2007 IEEE.

Amendment of cavity perturbation method for permittivity measurement of extremely low-loss dielectrics

To derive the expression for complex dielectric and magnetic susceptibilities, an easy and alternate approach is proposed. This analysis is based on the assumption that the cavity is equivalent to an isolated lumped resonant circuit. The results are identical with standard expressions. Results of a few samples are also tabulated. © 1989.
