Super Dielectric Materials [PDF]

Materials, 2014
Evidence is provided here that a class of materials with dielectric constants greater than 105 at low frequency (<10−2 Hz), herein called super dielectric materials (SDM), can be generated readily from common, inexpensive materials. Specifically it is demonstrated that high surface area alumina powders, loaded to the incipient wetness point with a ...

Modeling of the evolution of dielectric loss with processing temperature in ferroelectric and dielectric thin oxide films [PDF]

, 2008
It was experimentally found that the evolution of dielectric loss with processing temperature displays a common trend in ferroelectric and dielectric thin oxide films: firstly an increase and then a decrease in dielectric loss when the processing temperature is gradually raised. Such a dielectric response of ferroelectric/dielectric thin films has been

Towards all-dielectric metamaterials and nanophotonics [PDF]

arXiv, 2015
We review a new, rapidly developing field of all-dielectric nanophotonics which allows to control both magnetic and electric response of structured matter by engineering the Mie resonances in high-index dielectric nanoparticles. We discuss optical properties of such dielectric nanoparticles, methods of their fabrication, and also recent advances in all-

Screening of Coulomb interactions in liquid dielectrics [PDF]

, 2018
The interaction of charges in dielectric materials is screened by the dielectric constant of the bulk dielectric. In dielectric theories, screening is assigned to the surface charge appearing from preferential orientations of dipoles along the local field in the interface.

Dielectric anisotropy in polar solvents under external fields [PDF]

J. Stat. Mech. P08022 (2015), 2014
We investigate dielectric saturation and increment in polar liquids under external fields. We couple a previously introduced dipolar solvent model to a uniform electric field and derive the electrostatic kernel of interacting dipoles. This procedure allows an unambiguous definition of the liquid dielectric permittivity embodying non-linear dielectric ...

Dielectric properties of interacting storage ring plasmas [PDF]

Phys.Rev.E59:1015-1023,1999; Erratum-ibid.E69:039902,2004, 1998
A dielectric function including collisional correlations is derived by linearizing the self consistent Vlasov equation with a Fokker-Planck collision integral. The calculation yields the same type of dielectric function as in the standard-theory of Schottky-noise in storage rings. This dielectric function is compared with the Mermin-dielectric function

Dielectric mixtures -- electrical properties and modeling [PDF]

IEEE Trans. on Dielectrics and Electrical Insulation, vol.9 No.5, pp809-828, 2002., 2001
In this paper, a review on dielectric mixtures and the importance of the numerical simulations of dielectric mixtures are presented. It stresses on the interfacial polarization observed in mixtures. It is shown that this polarization can yield different dielectric responses depending on the properties of the constituents and their concentrations.

InN dielectric function from the midinfrared to the visible range [PDF]

, 2009
The dispersion of the dielectric function for wurtzite InN is analytically evaluated in the region near the fundamental energy gap. The real part of the dielectric function has a logarithmic singularity at the absorption edge. This results in the large contribution into the optical dielectric constant.

Universal Electromagnetic Waves in Dielectric [PDF]

Journal of Physics: Condensed Matter. Vol.20. No.17. (2008) 175223, 2009
The dielectric susceptibility of a wide class of dielectric materials follows, over extended frequency ranges, a fractional power-law frequency dependence that is called the "universal" response. The electromagnetic fields in such dielectric media are described by fractional differential equations with time derivatives of non-integer order.

On the Static Dielectric Permittivity for Coulomb System in the Long Wavelength Limit [PDF]

, 2009
On the basis of the exact relations the general formula for the static dielectric permittivity for Coulomb system is found in the region of small wave vectors. The obtained formula describes the dielectric function of the Coulomb system in both limits: in the "metallic" state and in the "dielectric" one.
