Abstract
The absorption of electromagnetic radiation in Dirac semimetals in a quantizing magnetic field has been considered. A universal broadening of the collisionless cyclotron damping line of electromagnetic waves at a decrease in the number of filled Landau levels has been revealed. New regimes of the propagation of electromagnetic waves and new accompanying effects have been found.
