Relative complex permittivity and its dependence on frequency

open access: yesWorld 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.

Determination of the Relative Permittivity of Acetylcholinesterase

The Journal of Physical Chemistry Letters, 2009
For a complete understanding of biomolecular functions, electrostatic interactions have to be characterized. These interactions are highly dependent on the relative permittivity of the surrounding medium, including the interior of proteins and binding site regions. However, determination of the relative permittivity is not trivial.

The relative permittivity of supercooled water

The Journal of Chemical Physics, 1978
Approximate relative permittivity data for water down to −35°C have been derived from measurements of the Maxwell–Wagner interfacial polarization which occurs at the surface of emulsified water droplets. Although the emulsifying agent strongly influences this polarization in a complex way, a novel method of data analysis enables the permittivity and ...

The permittivity of thermodynamically ideal liquid mixtures and the excess relative permittivity of binary dielectrics

Physical Chemistry Chemical Physics, 2009
The ideal relative permittivity of liquid mixtures is demonstrated to be a volume-fraction-weighted average of the pure-component relative permittivities. This generalised-thermodynamics result is used to define the molar electric dipole, permittivity, dielectric polarization and electric susceptibility of thermodynamically ideal liquid mixtures and ...
