Contents
The subject of this course is electromagnetic radiation. The course opens with a derivation of the retarded Green function from Maxwell’s equations. This Green function is used to derive the potential (Lienard-Wiechert) and radiation from an accelerated charge. The special case of a constant velocity larger than the speed of light in a medium leads to a qualitative description of Cerenkov radiation. The case of uniform circular motion is worked out to the point of a qualitative treatment of the power spectrum of cyclotron and synchrotron radiation. Other important examples that are treated in the course are radiation from scattering of light to a free electron. (Thomson and Compton scattering) and radiation from a collision of two charges (Bremsstrahlung). Finally the radiation of an oscillating charge distribution is treated in a multipole expansion up to the quadrupole term. An application is Rayleigh scattering and the structure function of a material. Level: Introduction to Jackson: “Electrodynamics”
