Applicability of point dipoles approximation to all-dielectric metamaterials [PDF]

open access: yes, 2015
All-dielectric metamaterials consisting of high-dielectric inclusions in a low-dielectric matrix are considered as a low-loss alternative to resonant metal-based metamaterials.

Tailoring Dielectric Properties of Multilayer Composites Using Spark Plasma Sintering [PDF]

open access: yes, 2007
A straightforward and simple way to produce well-densified ferroelectric ceramic composites with a full control of both architecture and properties using spark plasma sintering (SPS) is proposed. SPS main outcome is indeed to obtain high densification at

DIELECTRIC PROPERTIES OF POLYACETYLENE

open access: yesLe Journal de Physique Colloques, 1983
We present a theoretical first-principles anisotropic dielectric function for all-trans polyacetylene. This dielectric function is shown to describe the 8-9 eV dielectric response peak measured using electron energy-loss spectroscopy.

Effective Dielectric Constants of Photonic Crystal of Aligned Anisotropic Cylinders: Application to the Optical Response of Periodic Array of Carbon Nanotubes [PDF]

open access: yes, 2005
We calculate the static dielectric tensor of a periodic system of aligned anisotropic dielectric cylinders. Exact analytical formulas for the effective dielectric constants for the E- and H- eigenmodes are obtained for arbitrary 2D Bravais lattice and ...

Tailoring dielectric properties of ferroelectric-dielectric multilayers

open access: yesApplied Physics Letters, 2014
We develop a nonlinear thermodynamic model for multilayer ferroelectric heterostructures that takes into account electrostatic and electromechanical interactions between layers. We concentrate on the effect of relative layer fractions and in-plane thermal stresses on dielectric properties of Ba0.6Sr0.4TiO3-, BaTiO3-, and PbZr0.2Ti0.8O3 (PZT)-SrTiO3 ...

Signs of low frequency dispersions in disordered binary dielectric mixtures (50-50)

open access: yes, 2004
Dielectric relaxation in disordered dielectric mixtures are presented by emphasizing the interfacial polarization. The obtained results coincide with and cause confusion with those of the low frequency dispersion behavior.
