Abstract

I argue that the form of the macroscopic Poynting vector derived in my paper [M. G. Silveirinha, Phys. Rev. B 80, 235120 (2009)] is self-consistent with the usual form of the microscopic Poynting vector in nonmagnetic media, and that therefore there is no arbitrariness in the definition of the macroscopic Poynting vector as long as the usual expression for the microscopic Poynting vector is accepted as valid. I also emphasize that the macroscopic Poynting vector derived in my paper is coincident with the most general form of the Poynting vector reported in the literature for reciprocal stationary spatially dispersive media.
