I M Frank's papers on the radiation of sources moving in refractive media (the 'optics of moving sources')

摘要

A charged particle which travels through a refractive medium, i.e., a medium whose properties are defined by specifying its permittivity and permeability, becomes a source of electromagnetic waves. At the present time, the radiation of moving sources in different kinds of refractive media has become a rather vast field of physics. Extensive experimental and theoretical data have been accumulated in this field, and the results of investigators have led to significant application in physics.
