Labyrinthine Instability in Magnetic and Dielectric Fluids

When magnetic fluid is confined with an immiscible fluid between closely spaced parallel plates, and a uniform magnetic field is applied normal to the plates, the interface between the fluids exhibits a threshold instability in which a comblike pattern is established [1]. At supercritical intensities of the magnetic field a mutual invasion of the two phases occurs, in which fingers of magnetic ...

Static dielectric properties of dense ionic fluids.

The static dielectric properties of dense ionic fluids, e.g., room temperature ionic liquids (RTILs) and inorganic fused salts, are investigated on different length scales by means of grandcanonical Monte Carlo simulations. A generally applicable scheme is developed which allows one to approximately decompose the electric susceptibility of dense ionic fluids into the orientation and the distort...

Wave propagation in periodic nonlinear dielectric superlattices

Novel phenomena such as photo& band gaps and possible light localization occur when electromagnetic (EM) waves propagate in dielectric superlattices.1-6 In an approximation where only the scalar nature of the EM wave is taken into account, wave propagation in a periodic or disordered medium resembles the dynamics of an electron in a crystal lattice. As a result, photonic bands and gaps arise in...

Propagation of instability in dielectric elastomers

When an electric voltage is applied across the thickness of a thin layer of an dielectric elastomer, the layer reduces its thickness and expands its area. This electrically induced deformation can be rapid and large, and is potentially useful as soft actuators in diverse technologies. Recent experimental and theoretical studies have shown that, when the voltage exceeds some critical value, the ...
