ABSTRACT
The previous chapter contained a rather general account of the theory of the field generated by a moving charged particle. In the present chapter the fields associated with two relatively simple types of motion are considered in some detail, partly because they offer clear cut illustrations of the general theory and partly because they are the key to the understanding of important physical phenomena. The respective motions are uniform rectilinear and uniform circular. In the former there is no acceleration, and, of course, the particle does not radiate if it travels in a vacuum; but it can radiate by traveling in a medium of refractive index μ with a speed in excess of c/μ, and this is the so-called Čerenkov radiation process. In the latter motion the acceleration is that pioduced by a magnetostatic field, and the corresponding radiation may be called gyro radiation.
