The multi-species plasma of natural or laboratory origin is often considered to host nonlinear ion-acoustic waves. We present calculations ion fluxes induced by waves in a consisting multiple populations, electrons, and dust. following models are considered: an electron-ion with cold ions, bi-ion two types warm positively charged dusty plasma. It found that the plasma, wave-induced flux directe...

A rigorous theoretical investigation has been made on the nonlinear propagation of dust-ion-acoustic shock waves in a multi-component magnetized pair-ion plasma (PIP) having inertial warm positive and negative ions, inertialess non-thermal electrons positrons, static negatively charged massive dust grains. The Burgers’ equation is derived by employing reductive perturbation method. model suppor...

Externally driven, vertically polarized transverse dust-lattice waves were observed in a one-dimensional strongly coupled dust chain levitated in the plasma-sheath boundary of a dc argon plasma at low gas pressure around 5 mtorr. Real and imaginary parts of the complex wave number were measured in the experiments. The experimental result clearly shows that the observed transverse dust-lattice w...

We theoretically investigate conditions for the refraction of long-wavelength dust acoustic waves by arrays of periodic cylinders in a dusty plasma. This is based on a recent analysis of the refraction of shallow water waves by periodic cylinder arrays (Hu and Chan, Phys. Rev. Lett. 95 (2005), 154501). In the dusty plasma case, however, the boundary conditions involve the formation of voids aro...

Instability of high frequency wave, such as, Langmuir wave (LW) is studied using fluid model in collisional and streaming dusty plasma with dust charge fluctuation. In irradiated dusty plasma, dust charge fluctuation is considered to be due to the combined effect of LW perturbation and photoelectron emission. The piled up electrons on a dust grain due to LW perturbation can be swept out by phot...

Abstract The effects of dust-dust self-gravitational force and nonextensive characteristics plasma species on the low frequency twisted waves owing to helical wave structure in complex (dusty) plasmas are analyzed. electrons ions modelled by q-distribution function while massive dust particles Maxwellian distributed. incorporated Vlasov equation kinetic theory where perturbed distribution funct...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...
