Wake-induced bending of two-dimensional plasma crystals

Nonlinear Two - Dimensional Potential Plasma Wake Waves

The condition for potential description of the wake waves, generated by flat or cylindrical driving electron bunch in cold plasma is derived. The two-dimensional nonlinear equation for potential valid for small values of that is obtained and solved by the separation of variables. Solutions in the form of cnoidal waves,existing behind the moving bunch at small values of vertical coordinate,are o...

Two-dimensional dusty plasma crystals and liquids

Strongly coupled plasmas – in which the average potential energy per particle dominates over the average kinetic energy – appear in a wide variety of physical systems. Among these systems, dust plasma crystals and liquids realized in low-pressure gas discharges by dispersing mesoscopic grains into the plasma have attracted a lot of attention during the past years. We describe the experimental r...

Two - dimensional Stationary Wake Fields in Vortexfree Cold Plasma

Ground-state structures of superparamagnetic two-dimensional dusty plasma crystals.

Ground-state structures of finite, cylindrically confined two-dimensional Yukawa systems composed of charged superparamagnetic dust grains in an external magnetic field are investigated numerically, using molecular dynamic simulations and lattice summation methods. The ground-state configuration of the system is identified using, as an approximation, the experimentally obtained shape of the hor...

Two-Dimensional Photonic Crystals

This research investigates the use of two-dimensional (2D) photonic crystals (PhC) as selective emitters and means of achieving higher efficiencies in combustion-driven thermophotovoltaic (TPV) systems intended as auxiliary power systems in automobiles. A TPV power conversion system functions on the principle of direct conversion of thermal radiation into electricity. A basic TPV system consist...
