    Abstract

    We study the radiative decay and Purcell effect for finite-size electric and magnetic dipole emitters placed in an uniaxial medium. For both electric and magnetic dipoles, we find that the radiative rate is strongly enhanced in the hyperbolic regime, when the signs of the longitudinal and transverse dielectric constants are opposite. However, the behavior of the Purcell factor in the transition region from elliptic to hyperbolic regimes is very different for the electric and magnetic dipoles. The Purcell factor enhancement for magnetic dipole is weaker and it takes place only deep inside the hyperbolic regime, while for electric dipole the maximum enhancement is achieved at the transition boundary.
