Spontaneous radiation of a finite-size dipole emitter in hyperbolic media: "
Author(s): Alexander N. Poddubny, Pavel A. Belov, and Yuri S. Kivshar
We study the radiative decay and Purcell effect for a finite-size dipole emitter placed in a homogeneous uniaxial medium. We demonstrate that the radiative rate is strongly enhanced when the signs of the medium longitudinal and transverse dielectric constants are opposite, and that the isofrequency ...
