The Effect of Thickness and Extracting Technique for Dielectric Properties

The differences between extracting and measurement methods are presented which are used at millimeter wave frequency band (Ka and W bands), in this study. The common using measurement methods (Free Space Measurement, Waveguide, Coaxial Probe, and Resonant Cavity) are described with their features. In addition, the advantage of Newton-Raphson extracting technique is presented. Furthermore, the thickness effect is showed in process of obtaining the dielectric constant at Ka-band. Index Terms—Dielectric constant, free space measurement, genetic algorithm, newton-raphson method.
