Abstract

A simple yet powerful calibrationโ€independent method is proposed for complex permittivity extraction of dielectric materials. There are two main features of the method as follows: (a) it decreases any uncertainty arising from using a second (extra) sample and (b) it does not require precise location of the sample within its cell (a waveguide or coaxialโ€line section). The disadvantage of the method is that it may produce some singularity points while extracting the complex permittivity from measurements. We validated the method by calibrated and uncalibrated complex scattering parameter measurements of a polyvinylโ€chloride (PVC) sample at Xโ€band (8.2โ€“12.4 GHz). ยฉ 2009 Wiley Periodicals, Inc.

## Abstract There is a need for a method for the performance evaluation of calibrationโ€independent measurements of dielectric materials located into a measurement cell (a coaxial or waveguide section) before starting the extraction of the complex permittivity of the sample.
