Abstract: | The permittivity of an amorphous insulator consisting of several types of molecules is found. The concepts of polarizability averaged over molecule types and of polarizability fluctuation are introduced, which, when taken into consideration, impart dispersive properties to the permittivity of the medium. It is shown that, near the frequencies at which the average polarizability vanishes, the permittivity depends on the average quadratic fluctuation of the molecular polarizability. Anomalous electromagnetic waves in these frequency intervals are considered. |
