Solitary And Shock Waves

AbstractThe propagation of dust-ion-acoustic (DIA) solitary and shock waves in multi-ion (MI) unmagnetised and magnetised plasmas have been studied theoretically. The plasma system contains positively and negatively charged inertial ions, opposite polarity dusts, and high energetic super-thermal electrons. The fluid equations in the system are reduced to a Korteweg-de Vries (K-dV) and Korteweg-de Vries Burger (K-dVB) equations in the limit of small amplitude perturbation. The effect of super-thermal electrons, the opposite polarity of ions, and dusts in the solitary and shock waves are presented graphically and numerically. Present investigations will help to astrophysical and laboratory plasmas.

Electromagnetic Solitons

We show that atomic gasses can support solitary pulses of unipolar, non-oscillating EM-field ("EM-bubbles") of up to the atomic amplitude, with their length ranging from ~10−9 s to ~10−16 s , which propagate without dispersion and are stable and insensitive to the change of gas density. We found the condition on the atomic potential necessary for formation of EM-bubble. Atomic gasses can also support an EM shock which is a precursor of a cw ionizing field.
