Trapping and Acceleration of Electron by Elliptically Polarized Electromagnetic Wave Propagating Across Static Magnetic Field

摘要

Suppose that an electromagnetic wave propagating across a magnetic field beta sub 0 polarizes on a plane perpendicular to beta sub 0 and that its phase velocity is a little slower that the light velocity c. It is shown that such wave (EP-wave) can trap a charged particle and accelerate it unlimitedly. The well-known electrostatic and electromagnetic wave trapping accelerations are included as two limiting cases of this acceleration. A brief comment on how to create a slow wave by using a plasma is also presented.
