mixing formuladry snowrockdielectric mixturesdiscrete scatterersGeneral mixing formulas are derived for discrete scatterers immersed in a host medium. The inclusion particles are assumed to be ellipsoidal. The electric field inside the scatterers is determined by quasi-static analysis, assuming the diameter...
When the mate-rial is not isotropic, the individual components of the permittivity are given. A superscript S indicates a measurement made under constant strain ("clamped" dielectric constant). If the constraint is removed, the measurement yields ε T , the "unclamped" or free dielectric ...
This study adopts a multiscale approach to estimate the complex dielectric response of C-S-H over the 0 to 1000 GHz frequency range. We perform molecular dynamics simulations to compute the frequency -dependent dielectric response of water in C-S-H from the polarization correlation formula. We ...

where k is the dielectric constant, Ɛr is relative permittivity, Ɛm is the permittivity of material and Ɛo represents the permittivity of vacuum. In the presence of an electric field, the behavior of molecule/polymeric material is characterized by permittivity. The energy storage application...

It is also shown that the Maxwell Garnett formula is not nearly as accurate for this cluster lattice, also because of this enhancement effect. 展开 关键词: Theoretical or Mathematical/ composite materials dielectric materials permittivity/ permittivity isotropic lattice multiphase lattice conducting ...
Moreover, the associated density of charge is not in if the crystal exhibits anisotropic dielectric properties. These results are obtained by analyzing, for a small defect ν, the linear and nonlinear terms of the resolvent expansion of . Second, we show that, after an appropriate rescaling, ...
The electric field distribution which is produced by the dielectric Sphere with an eccentric sphere inclusion in influence of the uniform external field is discussed by mean of the methods of variable separation, series expanding and the introductive conception of the effective permittivity. The ...
Permeability is largely dependent on the size and shape of the pores in the substance and, in granular materials such as sedimentary rocks, by the size, shape, and packing arrangement of the grains. Is paper a dielectric material? More commonly used as a writing support and in packaging, pap...
