Description
The Coulomb field of the charged particle in the medium is known to be
shielded, due to the response of the material. In this research, we
show that, unexpectedly, for the relativistic charge moving inside the
medium it is possible that at certain conditions the Coulomb field
will be enhanced rather than weakened! This phenomenon is predicted
theoretically; we also simulated this process in CST, and the results
have confirmed our conclusions. This effect can play a vital part for
qualitative understanding of the processes of dynamic polarization
of the medium by relativistic charged particle beams, especially when
they generate radiation.
