Poynting theorem constraints on the signs of the imaginary parts of the electromagnetic constitutive parameters: comment
Contrary to an unphysical conclusion obtained by Alavikia et al. [J. Opt. Soc. Am. A32, 522 (2015)JOAOD60740-323210.1364/JOSAA.32.000522], the imaginary parts of both the permittivity and the permeability of any linear, homogeneous, passive, spatially local, dielectric-magnetic material are always p...

| Zusammenfassung: | Contrary to an unphysical conclusion obtained by Alavikia et al. [J. Opt. Soc. Am. A32, 522 (2015)JOAOD60740-323210.1364/JOSAA.32.000522], the imaginary parts of both the permittivity and the permeability of any linear, homogeneous, passive, spatially local, dielectric-magnetic material are always positive, independent of the signs of their real parts. |
