Performance Evaluation of Volumetric Water Content and Relative Permittivity Models [PDF]
The Scientific World Journal, 2013 In recent years many models have been proposed for measuring soil water content (θ) based on the permittivity (ε) value. Permittivity is one of the properties used to determine θ in measurements using the electromagnetic method.

A Broadband Stripline Technique for Characterizing Relative Permittivity and Permeability [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2018 We present a stripline design and calibration method allowing the extraction of relative permittivity of single dielectric samples in the 200-MHz–50-GHz range. The simultaneous extraction of relative permittivity and permeability is also illustrated by characterizing a set of samples comprising magnetic inclusions over the same frequency range.

Relative permittivity in the electrical double layer from nonlinear optics [PDF]
The Journal of Chemical Physics, 2018 Second harmonic generation (SHG) spectroscopy has been applied to probe the fused silica/water interface at pH 7 and the uncharged 11¯02 sapphire/water interface at pH 5.2 in contact with aqueous solutions of NaCl, NaBr, NaI, KCl, RbCl, and CsCl as low as several 10 μM. For ionic strengths up to about 0.1 mM, the SHG responses were observed to increase,
