Abstract

The dispersion relation for polaritons in a crystal slab of an arbitrary thickness is derived by the quantum Green function method. The equation is reduced to the classical electrodynamics form with an effective dielectric function depending on the crystal thickness. The energy and the radiation damping of polariton modes in thin anthracene crystals are calculated and compared with the experimental values based on the studies of low‐temperature luminescence and refractive index dispersion.
