Radiation from Moving Charges

One of the most important consequences of Maxwell’s equations is the emission of electromagnetic radiation by charged particles in accelerated motion. In this chapter we will give a classical description of this phenomenon, emphasizing the general characteristics of the cross sections and the spectral and polarimetric properties of the radiation emitted, for both relativistic and nonrelativistic particles. In particular, we will describe some fundamental physical processes such as Thomson and Rayleigh scattering and give an in-depth discussion of the bremsstrahlung radiation (in nonrelativistic approximation), of the cyclotron radiation and of the synchrotron radiation. The last part of the chapter is dedicated to the study of the radiation due to a large number of particles and its multipole expansion.
