An explicit integral representation by single definite integrals of the fundamental matrix (Green's tensor) of the time-dependent system of hexagonal elastic media is derived. Thereby the problem of internal conical refraction in such media is solved.
Keywords: fundamental matrix; Green's tensor; transversely isotropic media; hexagonal crystals; wave propagation; conical refraction; wave-front lids.
