Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Calculation of electromagnetic field energy in a medium with temporal and spatial dispersion outside the
transparency domain is discussed. It is shown that charged particle contribution to the energy of electromagnetic
perturbations in the general case can be described in terms of a bilinear combination of the dielectric polarizability
of the medium. The explicit form of such contribution is found. The relations obtained are used to generalize the
Planck law and Kirchhoff law to the case of an absorptive medium with spatial dispersion. |
