Electrostatic Solitary Waves in Multicomponent Nonthermal Plasma
A systematic investigation has been made of ion-acoustic solitary waves in plasma consisting of cold positively and negatively charged ions, as well as nonthermal electrons. The basic features of the solitary waves are investigated by using the reductive perturbation method, which is valid for the small but finite amplitude waves. Computational investigations have been performed to examine the ...
متن کاملNon Linear Effects Produced by Electrostatic Waves in a Magnetized Plasma
Some non-linear phenomena, like ponderomotive effects and parametric decays, produced by high power electrostatic waves in a magnetized low density plasma, have been investigated experimentally. The injection of high power electrostatic waves into a plasma causes ponderomotive forces arise. Their action primarily gives rise to a plasma density depletion in front of the launching system and subs...
متن کاملNon-linear transient waves
This dissertation presents the results of a new study on 2-D transient waves, formed through the focusing of wave energy. An extensive laboratory investigation has been undertaken for large number of wave groups with a range of amplitudes and frequency bandwidths. The results show that the focusing of wave energy can produce highly non-linear wave groups, where the nonlinearity increases with a...
متن کاملLarge‐amplitude electrostatic waves observed at a supercritical interplanetary shock
[1] We present the first observations at an interplanetary shock of large‐amplitude (> 100 mV/m pk‐pk) solitary waves and large‐amplitude (∼30 mV/m pk‐pk) waves exhibiting characteristics consistent with electron Bernstein waves. The Bernstein‐like waves show enhanced power at integer and half‐integer harmonics of the cyclotron frequency with a broadened power spectrum at higher frequencies, co...
متن کاملShock Waves
Shock wave theory was first studied for gas dynamics, for which shocks appear as compression waves. A shock wave is characterized as a sharp transition, even discontinuity in the flow. In fact, shocks appear in many different physical situation and represent strong nonlinearity of the physical processes. Important progresses have been made on shock wave theory in recent years. We will survey th...
