On the electrodynamics of continuous media

Radiation of fast charged particles in the presence of the interface between hollow space and “left-handed” ferrodielectric is considered. The quantitative identity of various phenomena in the case of “different-right-handed” media is revealed. It is shown that transition radiation at the interface with a “left-handed” medium is quantitatively identical to the case of annihilation radiation at the interface with a “right-handed” medium with participation of various charged particles. Transition radiation of the charged particle at the interface with a uniaxial crystal is generalized to radiation with participation of particles with various charges and velocities.
