Module description
This module develops Maxwell's equations and their application to electromagnetic waves. The full theory of transmission, reflection, dispersion and absorption of electromagnetic waves is developed for free-space, conductors and dielectrics. The concept of retarded potential is applied to normal radiation from antennas and to synchrotron radiation from relativistic electrons. The scattering of electromagnetic waves by electrons is discussed.
