Nonlinear equations governing the characteristics of tripolar vortices (TPVs) are investigated in an inhomogeneous magnetoplasma having inertialess non-Maxwellian electrons that obey Cairns, kappa, and (r, q)-distributions. Analytical numerical solutions nonlinear presented for various possible cases. In this regard, dispersion relation drift ion-acoustic waves (IAWs) is derived, condition desc...

Results are presented from an experiment in which two plasmas, initially far denser than a background magnetoplasma, collide as they move across the magnetic field. The dense plasmas are formed when laser beams, nearly orthogonal to the background magnetic field, strike two targets. The merging plasmas are observed to carry large diamagnetic currents. A reconnection event is triggered by the co...

2014 By using a full electromagnetic-wave theory, an analysis is made of the ELF/VLF radiation resistance of a finite electric dipole, oriented at arbitrary angle in a cold, uniform magnetoplasma. The general integral expression for the radiation resistance R is derived, and from that, various approximate closed forms of R are obtained for the entire VLF/ELF range. Numerical plots of R are give...

We present a study of the electron magnetohydrodynamics Grad–Shafranov (GS) reconstruction diffusion region (EDR) magnetic reconnection. Two-dimensionality magnetoplasma configuration and steady state are two basic assumptions GS technique, which represent method’s fundamental limitations. The demonstrates that can provide physically meaningful results even when these assumptions, hardly fulfil...
