In a recent paper [J. Opt. Soc. Am. B 29, 1799 (2012)], to construct the electromagnetic fields of the confined point dipole inside a dielectric cavity, the scattering-superposition method is used incorrectly, and the boundary conditions also are not satisfied. Therefore, the Purcell factor obtained in this paper must be misleading.
