Splitting of Vavilov-Čerenkov radiation spectra in excited dispersing media
- 15 Downloads
Within the framework of quantum electrodynamics, the additional mechanism of shaping Vavilov-Čerenkov radiation, characteristic for excited media and not described by their refractive index, is examined. Its interference with the usual generation channel under stationary homogeneous conditions can eliminate the spectrum splitting detected earlier theoretically. Splitting is restored in inhomogeneous situations. The time inhomogeneity is analyzed.
