Title: Whistler waves produced by a modulated spiraling electron beam: Linear approach

Abstract

The theory of whistler wave interaction with a modulated electron beam injected obliquely to the magnetic field in an unbounded space plasma is considered. The study of the energy transfer between the spiraling beam and the whistler wave is done in the case of sheared whistlers, when the parallel wave number is very small compared to the perpendicular one. In the linear regime, structures of potentials and electromagnetic fields in the beam vicinity and in the wave zone are obtained analytically: Simple expressions for field components are provided for {hacek C}erenkov and Doppler resonances, in double and single pole cases. Emitted power is calculated as a function of beam parameters. {copyright} {ital 1996 American Institute of Physics.}
