Instabilities of Surface Waves
1995Low-temperature plasmas have been of much interest recently because of their usefulness in many technological applications of plasmas for which very high temperatures such as those in fusion plasmas are not required. Unlike hot plasmas, which must be confined by strong magnetic fields, most low-temperature laboratory plasmas are bounded by rigid ...

Surface Instabilities of Ferrofluids
2008We report on recent progress in understanding the formation of surface protuberances on a planar layer of ferrofluid in a magnetic field oriented normally to the surface. This normal field or Rosensweig instability can be tackled by a linear and a nonlinear description.

Electric-field–driven instabilities on superhydrophobic surfaces
EPL (Europhysics Letters), 2011We study possible mechanisms of the transition from the Cassie state to the Wenzel state on superhydrophobic surfaces under the influence of electric fields as a function of the aspect ratio and the wettability of the surface. A simple analytical model for axisymmetric cavities and small deflections of the liquid menisci within the cavities reveals the

Taylor instability of finite surface waves
Journal of Fluid Mechanics, 1960The instability of the accelerated interface between a liquid (methanol or carbon tetrachloride) and air has been investigated experimentally for approximate sinusoidal disturbances of wave-number range from well below to well above the cut-off. The growth rates are measured and compared with theoretical results.

Electrostatic field-induced surface instability
Applied Physics Letters, 2004We examine the thermodynamics and evolution of the morphology of a metal surface in the presence of a large electric field. A flat surface is unstable for all finite electric fields E with a critical wavelength proportional to E−1 or E−2 at small and large fields, respectively.

Surface instability of polymer gels
Phase Transitions, 1994Abstract We consider polymer gels immersed in a solvent and deformed uniaxially. The free surfaces of such gels can become unstable against surface corrugations with lowering of the temperature or increasing of the degree of uniaxial anisotrophy.

INSTABILITY OF PLANING SURFACES
1969Abstract : A mathematical analysis is developed for the hydrodynamic problem of a two-dimensional planing surface which is heaving sinusoidally. From the assumptions of small angle of attack and small amplitudes of motion, it is possible to formulate a linear problem. Gravity is neglected.

Instabilities and Surface Tension
1988I shall present below recent progress made in the study of the effect of surface tension on various instabilities. The attention will be on two well known physical phenomena: Saffman-Taylor fingers in long rectangular channels and needle crystals growing at the expanse of a supercooled melt.
