Electrostriction in As2Se3-PMMA Microtapers [PDF]

, 2019
Electrostriction is the tendency of materials to acquire a fluctuation in density in the presence of coherent electro-magnetic fields. It leads to a change in the refractive index of the material, which can be explained in the language of nonlinear ...

Tuning electro-thermo-mechanical coupling in electroactive nanocomposites for self-oscillating solid-state heat pumps

npj Flexible Electronics
Solid-state cooling based on the electrocaloric effect (ECE) offers low power consumption and zero greenhouse gas emissions. Among various designs of electrocaloric cooling devices, the flexible self-oscillating EC heat pumps, enabled by synergistic ECE ...

Electrostrictive Mechanism of Radiation Self-Action in Nanofluids

Advances in Condensed Matter Physics, 2013
The electrostriction mechanism of beam self-focusing in nanofluids is theoretically investigated. An analytical solution of the diffusion equation, which describes the dynamics of particles in nanofluids, was obtained and studied.

The role of electrostriction on the stability of dielectric elastomer actuators

, 2014
In the field of soft dielectric elastomers, the notion ‘electrostriction’ indicates the dependency of the permittivity on strain. The present paper is aimed at investigating the effects of electrostriction onto the stability behaviour of homogeneous ...

Anomalies of the temperature dependence of electrostriction in blue phases

, 1993
We investigated the field-induced shift of the blue phase diffraction bands. The temperature dependence of the electrostriction tensor components is determined for the first time.

Impact of electrostriction-induced acoustic interactions on transmission performances of WDM signals over standard fibers

, 2006
International audienceWe study the effect of power and phase distortions as induced by cross-phase modulation and electrostrictive nonlinearity in dispersive optical fibers. We obtain, evaluate, and discuss simple analytical expressions for the intensity

A thermodynamic approach to studying the influence of viscoelasticity on the apparent coefficient of quadratic electrostriction

, 1996
A problem encountered in quadratic electrostriction research in polymers is that viscoelasticity is usually not taken into account in theoretical predictions of intrinsic electrostriction whereas the apparent value obtained by experiment is a ...

Direct measurement of electrostriction in optical fibers

, 1998
The electrostriction contribution to the nonlinear refractive index in optical fiber was theoretically calculated and measured. Nonlinearity was induced directly by insertion of the optical fiber into an intense external electric field.
