Space and Ground-based Observation of Mesoscale Convective System Thunderstorms Lightning On March 4, 2019, a lightning bolt lit up the sky over Argentina and lasted a mind-boggling 16.73 seconds. A lightning bolt on October 31, 2018 also set the new record in channel length. It stretched 709 kilometres from the Atlantic Ocean, across the part …

Programmable Electro-Mechanical Dust Dispenser for Dusty Plasma Experimental Device An electro-mechanical dust dispenser has been designed and developed for dropping dust into the plasma in dusty plasma experimental setup. Mechanical setup of the dust dispenser has been developed and fabricated in the laboratory. The frequency of vibration and amplitude of the developed dust dispenser can …

Study of a dusty plasma sheath in presence of a non-uniform magnetic field In plasma processing devices, negatively charged dust particles appear as contamination in etching, sputtering, and deposition processes. The dynamics of the dust particles at the edge region of the plasma play an important role in such processes. The present study deals with …

Study of Damping of Ion Acoustic Waves in Two-Electron Temperature Plasma Plasmas having more than one electron group with different temperatures and densities are frequently observed in laboratories as well as in space environment. The characteristics of this type of plasmas are found to be different than that of a normal electron-ion plasma. Such a …

Soliton in Inhomogeneous Plasma In laser plasma interaction, plasma is both inhomogeneous and nonlinear to large amplitude plasma waves. The large amplitude wave packet modifies the plasma density through the action of ponderomotive force. Soliton propagation and the dynamics in inhomogeneous plasma can be described by the inhomogeneous Nonlinear Schrodinger Equation. Accelerating stable pulses in …
