On the measurement of the dielectric constants of liquids, with a determination of the dielectric constant of benzene [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1929
Abstract It has long been recognised that the dielectric constant of a substance gives an important indication of its constitution, and the classical papers of Nernst and Drude giving methods for the determination of dielectric constants, have been followed by a long series of papers giving the dielectric constants of several hundreds

Dielectric Constant of Liquids (Fluids) Shown to be Simple Fundamental Relation of Density over Extreme Ranges from - 50^o^ to + 600^o^C, Believed Universal

open access: yes, 2008
Examinations of past complex theoretical equations describing isothermal dielectric constants (_[epsilon]_) of liquids show that none describe experiments throughout and that only a two-constant equation of density is required.

Estimation of Dielectric Properties of Cakes Based on Porosity, Moisture Content, and Formulations Using Statistical Methods and Artificial Neural Networks

open access: yes, 2008
Dielectric constant (DC) and dielectric loss factor (DLF) are the two principal parameters that determine the coupling and distribution of electromagnetic energy during radiofrequency and microwave processing.

Dielectric Properties of Azo Polymers: Effect of the Push-Pull Azo Chromophores

open access: yesInternational Journal of Polymer Science, 2018
The relationship between the structure and the dielectric properties of the azo polymers was studied. Four azo polymers were synthesized through the azo-coupling reaction between the same precursor (PAZ) and diazonium salts of 4-aminobenzoic acid ethyl ...

Improved dielectric properties achieved by blending PP and PVDF

open access: yesIET Nanodielectrics, 2019
Polymer films composed of polypropylene (PP) and poly(vinylidene fluoride) (PVDF) have been fabricated by extrusion with filming system. Owing to the low content of crystallites and the lubricant of carbon black, the commercial product PVDF 370 can be ...

Effects of Mixture Composition and Time on Dielectric Constant of Fresh Concrete

open access: yes, 2007
The strength and durability properties of concrete are related to its water to cement ratio. Previous studies have shown that electrical properties of concrete appear to be related to both the water and cement contents of a mixture as well. In this study,

Structural phase transition and dielectric relaxation in Pb(Zn1/3Nb2/3)O3 single crystals [PDF]

open access: yes, 2005
The structure and the dielectric properties of Pb(Zn1/3Nb2/3)O3 (PZN) crystal have been investigated by means of high-resolution synchrotron x-ray diffraction (with an x-ray energy of 32 keV) and dielectric spectroscopy (in the frequency range 100 Hz–1 ...

An Enhanced Saline Soil Dielectric Constant Model Used for Remote Sensing Soil Moisture and Salinity Retrieval

open access: yesRemote Sensing
The soil dielectric constant model is essential for retrieving soil properties based on microwave remote sensing. However, the existing saline soil dielectric constant models perform poorly in simulating the dielectric constant of soil with high water ...
