The permittivity of a suspension treated as a system of hard spheres is calculated in the Born approximation. The structure of the suspension is described by the Percus-Yevick correlation function. The permittivity of the system under consideration is expressed through a nonlocal susceptibility whose spatial extension is determined by the form factor ...

Determination of the Relative Permittivity of Acetylcholinesterase
The Journal of Physical Chemistry Letters, 2009For 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.

Optimization Techniques on Permittivity Distribution in Permittivity Graded Solid Insulators
Conference Record of the 2006 IEEE International Symposium on Electrical Insulation, 2006We have proposed a new concept for solid insulation; an application of FGM (functionally graded materials). By controlling the distribution of dielectric permittivity inside solid insulators, we can achieve the efficient field control with keeping simple configuration of solid insulators.

Microwave permittivity of dry sand
IEEE Transactions on Geoscience and Remote Sensing, 1998The relative dielectric constant, or relative permittivity, /spl epsiv/ of dry snow, is independent of frequency from about 1 MHz up to the microwave range of at least 10 GHz. New measurements of with improved accuracy were made with a specially designed resonator operating near 1 GHz.

Biomass measurement by inductive permittivity
Biotechnology and Bioengineering, 1997An electrodeless, inductive permittivity probe is shown to reliably indicate fermentation biomass. By designing the probe based on electromagnetic induction, the electrode polarization artifact-common to electrode-based permittivity measurements of conductive solutions-is eliminated. The measurement of viable biomass concentration (X(V)) is precise and

ENHANCING THE DIELECTRIC PERMITTIVITY OF ELASTOMERS
2008The electromechanical transduction properties of any dielectric elastomer are intrinsically regulated by the dielectric permittivity of the material. This parameter proportionally controls both the achievable active stresses and strains. Accordingly, a suitable increase of the material permittivity may provide a valuable means to improve the ...
