Test Particle Correlation by a Whistler Wave in a Nonuniform Magnetic Field.

Abstract

This paper presents computer simulations of the correlation in phase of test electrons in a monochromatic whistler wave propagating along a non-uniform external magnetic field. The behavior of resonant electrons depends on an inhomgeneity ratio R, which defines the external field gradient in relation to the wave amplitude. In the case abs. val. R <1, where electron trapping is possible, a hole (or an island) of particles is found to occur in phase plots of the distribution function. This causes the appearance of a transverse current coherent with the wave, which is most intense for abs. val. R approx. = or < 0.6. The significance of these results to magnetospheric propagation of a quasi-monochromatic whistler pulse is discussed. (Author)
