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.

Effect of Fiber Content and Temperature on the Dielectric Properties of Kenaf Fiber-filled Rigid Polyurethane Foam

open access: yesBioResources, 2014
Kenaf fiber-filled polyurethane foams were prepared using the free rising method. The dielectric constants and the loss tangents of the composites were studied as functions of fiber content (0, 5, 10, and 15 parts per hundred of polyols by weight ...

A THEORY ON DIELECTRIC LOSS

open access: yesActa Physica Sinica, 1984
In this paper, the transition probability distribution function including two parameters is derived using the whole Wigner function. The Jonscher's empirical formula of dielectric loss can be interpreted. This is a improvement on Ngai's theory of dielectric loss.

Anomalous localized resonance using a folded geometry in three dimensions [PDF]

open access: yes, 2013
If a body of dielectric material is coated by a plasmonic structure of negative dielectric material with nonzero loss parameter, then cloaking by anomalous localized resonance (CALR) may occur as the loss parameter tends to zero.
