One modification for this equation replaces the square of the index of refraction by the real part of a dielectric function.
One modification for this equation replaces the square of the index of refraction by the real part of a dielectric function. The standard version of this equation addresses the infinite-track case, but for finite-track conditions in the Franhoufer limit, the primary difference is that the frequency dependence with flux is proportional to frequency squared. One of its namesakes, along with Sakharov, proposed an idea for a controlled thermonuclear fusion reactor, the Tokamak. It sets the average number of photoelectrons observed, N equal to 370 times the path length L times the integral of the detection efficiency, epsilon, times sine squared theta. Its formulators were awarded the Nobel Prize in 1958 along with its associated? phenomenon's namesake.  For 10 points, name this doubly eponymous equation that determines the radiation a charged particle emits as moves through a medium at superluminal velocity, Cherenkov radiation.
