Book excerpt: Excerpt from Cerenkov and Sub-Cerenkov Radiation From a Charged Particle Beam In previous work? We have given a form for the Cerenkov radiation from periodic electron bunches propagating in a homogeneous medium. The method involved construction of the Fourier components of the field which in turn led to the Poynting vector expressed as harmonics of the basic electron beam frequency. The important results were that the Cerenkov cone angle is shifted substantially beyond the ordinary Cerenkov angle 60, (00560 and broadened so that a significant fraction of the power radiated appears at angles other than 60. As either frequency or the path length of the beam increases, the cone angle was found to approach 60 with an increasing fraction of the total radiation being radiated at that angle.
