Abstract

The dispersion equation in the problem of electromagnetic field stability in an infinite inverted homogeneous medium is analyzed rigorously. The instability region for small quantum numbers k is established. It is found that, in contrast to the prevailing opinion, a continuous transition is also possible between polariton waves and electromagnetic waves upon a gradual variation of k; in this case, the two types of waves cannot be separated.
