论文摘要
提出了在透明域之外的电磁场能量的一般关系。结果表明，可以用介质的介电极化性的双线性组合来描述带电颗粒对电磁扰动能量的贡献。发现这种贡献的明确形式。获得的关系用于将普朗克法律推广到吸收培养基的情况下。
General relations for electromagnetic field energy outside the transparency domain are proposed. 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 to the case of an absorptive medium.
