Fermi generalized this formula for the case of non-transparent media.
Fermi generalized this formula for the case of non-transparent media. The Landau method, which measures the work done by an electric field, is an alternative to this formula, which is useful in the millimeter wavelength range and assumes an infinite track length. It is based on calculating the energy loss of the flux of the Poynting vector over a cylindrical surface. Formulated in 1937, this formula measures a phenomenon that results when a charged particle moves through a medium at a superluminal velocity. For 10 points, name this doubly-eponymous formula used to calculate the amount of Cherenkov radiation emitted.
