Wo obtain therefore instead of Onsager's formula: the following expression: where μ denotes the permanent moment of an isolated molecule (that is, measured in the vapour state), &epsiv is the dielectric constant of the liquid, n is its refractive index (for λ = ∞) and N is the ...
This invention deals with novel method and apparatus for highly polarizable high dielectric constant positioning and motion control of the elements (approximately planar mirrors) of a Fresnel reflector solar concentrator tracking heliostat array wherein the elements are suspended with the center of mass ...
εij and \({\varepsilon }_{ij}^{0}\) are the total local strain and eigenstrain, respectively, Ei is the electric field component, ε0 is the vacuum permittivity, and κij is the background dielectric constant. The Landau energy density fLand is expressed as: $${f}_{{{\rm{Land}...
dielectric constantanomalyThe dielectric anomaly in ferroelectric liquid crystals, showing polarization inversion, is observed as functions of temperature and external field. The dielectric constant shows an anomalous nonlinear behavior as a function of the electric. In describing the dielectric anomaly, the...
