ABSTRACT
For most practical applications, one is interested in the frequency spectrum of the power radiated by high energy electrons. This chapter discusses the range of important harmonics. The continuing increase in the power radiated into higher and higher harmonics must break down, since the total power radiated is finite. The chapter discusses the integral representation for the Bessel function and provides qualitative discussion of the high energy power spectrum. It also discusses stationary phase contour and examines the angular distribution in the high energy limit. The degree of polarization increases with the speed of the charged particle. This characteristic distinguishes synchrotron radiation from thermal radiation, and was, for example, the clue to understanding the origin of the nonthermal radiation emitted by the Crab Nebula. The chapter discusses the directionality of synchrotron radiation.
