Abstract
An investigation is made of the properties of quasioptical electromagnetic beams that propagate in anisotropic media in a special direction — the direction of conical refraction — and are formed by plane waves that are concentrated near the surface of the cone of external conical refraction. The field structure of such beams is analyzed, and it is shown that they spread more slowly than is the case in the conventional directions (specifically, in free space).
