Abstract : We proposed in a previous paper Opt. Commun. 228, 33 2003 a modified radiative transfer equation to describe radiative transfer in a medium with a spatially varying refractive index. The present paper is devoted to the demonstration that this equation perfectly works in the non-absorbing - non-scattering limit, what was contested by L. Martí-López and coworkers Opt. Commun. 266, 44 2006. The assertion that this equation would imply a zero divergence of the rays is also commented.
