Relative complex permittivity and its dependence on frequency

World Journal of Engineering, 2017
Purpose This paper aims to give a brief overview of dielectric properties, relative complex permittivity and its dependence on frequency. The significance of different approaches to complex permittivity is also discussed. Design/methodology/approach The different mechanisms of polarization are then presented.

Characterization of Relative Complex Permittivity and Permeability for Magneto-Dielectric Sheets

IEEE Transactions on Electromagnetic Compatibility, 2018
A new method is developed to extract relative complex permittivity and permeability of magneto-dielectric sheets. Two test fixtures are used to separately extract electric and magnetic properties of the material under test (MUT).

Complex relative permittivity analysis for monitoring watermelon

2017 International Symposium on Antennas and Propagation (ISAP), 2017
This paper proposes a study of complex relative permittivity (∊ r =∊ r ′-j∊ r ″) for monitoring watermelon. The complex relative permittivity of peel and pulp are analyzed as variation of maturity stages and used for determining mature fruit of watermelon from the measured reflection coefficient.

Effect of porosity, pore size and permeability on the complex relative permittivity of sandstone

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.

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.
