Strange and quasiundulator radiation
Abstract
The condition for the electric field vector that must be satisfied for strange electromagnetic waves (SEM waves) to exist is given. It is noted that waves of this type are emitted by unconfined charged particles in external fields whose velocities before entering and after leaving the external fields are not equal (Bessonov, 1981). The angular spectrum and polarization properties of SEM radiation at frequencies omega are determined by the strangeness vector I. It is possible for light to be emitted as a series of wave trains, each being an SEM wave. Radiation in which the duration of the trains is short in comparison with the time interval separating the trains may be emitted even if the motion of the particles is finite. Three examples are considered. In the first, the external magnetic field is uniform, with a given intensity and spatial extent. In the second, it is assumed that the magnetic field is uniform in two regions of space separated by a gap of a certain length. In the third, it is assumed that the magnet in the first example is positioned at the center of the straightline gap of a synchrotron.
