Mechanical and Dielectric Properties of Low Permittivity Dielectric Materials
MRS Proceedings, 1996AbstractThe dielectric and mechanical properties of low permittivity dielectric/metal system consisting of fluoropolymers and copper were studied. The types of polymers in this study include sputtered Teflon, plasma-deposited fluoropolymers and the soluble Teflon AF1600.

Effective permittivity of dielectric mixtures
IEEE Transactions on Geoscience and Remote Sensing, 1988General 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 of the inclusion particles to be much smaller than one wavelength.

Dielectric permittivity of suspensions
Journal of Experimental and Theoretical Physics, 2007A strict macroscopic analysis of the limiting long-wavelength permittivity of a model suspension is presented in which the suspension is considered as a finely dispersed system consisting of isotropic dielectric balls with piecewise-continuous radial permittivity profile. The analysis is performed within the framework of the notion of compact groups of

Generalized dielectric permittivity of ice
JETP Letters, 2015The generalized dielectric permittivity describes the electric response of both bound charges (normal dielec tric constant) and free charges (conductivity). The generalized dielectric permittivity of ice (water) has been calculated within the model of classical quasiparticles as a function of the wave vector and frequency (q, ω).

Abstract This chapter discusses high permittivity dielectrics such as hafnium oxide and zirconium oxide and how the phonons of such materials, their band and polarization behavior and silicon interact. High permittivity materials are used as dielectrics with semiconductors.

High-permittivity relaxation dielectrics
Proceedings of the IEE - Part B: Electronic and Communication Engineering, 1962The dielectric properties of ceramic materials based on bismuth-strontium titanate are described, and the special features which characterize these materials discussed. Dielectric saturation measurements with high a.c. and d.c. fields are used to illustrate some of the difficulties which arise if the dielectric properties are described in terms of a ...

The permittivity of polar dielectrics
Russian Journal of Physical Chemistry A, 2007The best known works on the theory of permittivity of polar dielectrics are considered. Equations are obtained that relate the dipole moment of a molecule in a medium to substance permittivity and can be used in calculations of the polarization characteristics of rarefied gases and condensed polar dielectrics.

Dielectric permittivity profiles of confined polar fluids
The Journal of Chemical Physics, 2005The dielectric response of a simple model of a polar fluid near neutral interfaces is examined by a combination of linear response theory and extensive molecular dynamics simulations. Fluctuation expressions for a local permittivity tensor ϵ(r) are derived for planar and spherical geometries, based on the assumption of a purely local relationship ...

Enhancement of parallel (x-y plane) dielectric permittivity of confined fluids has been shown previously. However, a theoretical model that explains this enhancement is lacking thus far. In this study, using statistical-mechanical theories and molecular dynamics simulations, we show an explicit relation between the parallel dielectric permittivity ...
