Two coupled nonlinear equations for a perturbed electromagnetic field in an electron-positron-ion plasma with shear flow, embedded in a nonuniform magnetic field, are derived and solved analytically. The nonlinear solutions of these equations are found in the form of tripolar vortices. The linear...
Backreflection of short, intense laser pulses at oblique incidence on solid targets is explained with a model where a periodic electron density modulation acts as a diffraction grating. The pump and reflected electromagnetic waves drive through the ponderomotive force the grating, and the coupled...
