Effect of porosity, pore size and permeability on the complex relative permittivity of sandstone [PDF]
2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017 The measurement of the frequency dependences of the complex relative permittivity (CRP) of fully or partially saturated with distilled water rocks with different petrophysical characteristics is carried out. NMR relaxometer is used to determine the rocks pore size and porosity.

The Contemporary Definition of Complex Relative Permittivity
Journal of ASTM International, 2008 Abstract ASTM D150 [Standard Test Methods for AC Loss Characteristic and Permittivity (Dielectric Constant) of Solid Electrical Insulation, 2004] is the standard for measurement of alternating current (AC). Aimed at an analysis of this standard and proceeding from the information transmission characteristic of the dielectric, the ...

A new measurement technique for obtaining the complex relative permittivity of terrain surfaces
IEEE Transactions on Geoscience and Remote Sensing, 2002 A new method for measuring the effective complex relative permittivity of a reflecting surface is presented. The approach is based on the two-ray model. We derive an equation of a circle representing the complex reflection coefficient which relates the incidence angle, frequency, and received power from the path gain using the two-ray model.

Equations for Complex Relative Permittivity of Saline Water
IETE Technical Review, 1988 Equations hare been presented to calculate the complex relative permittivity of saline water as a function of salt content and temperature of water. The results obtained from these equations show good agreement with the published measured data.

IEEE Transactions on Terahertz Science and Technology, 2014 For measuring complex relative permittivity of more than 300 GHz in the THz region, time-domain spectroscopy (TDS) is usually used. On the other hand, a free-space method using a vector network analyzer (VNA) is used below 300 GHz. However, these methods have not been compared and continuity of complex relative permittivity measurement around 300 GHz ...
