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.
Learning outcomes
After taking this module students should be able to:
-
understand the fundamental theoretical basis for electromagnetic waves.
-
understand the propagation of plane electromagnetic waves in both free space and media and their behaviour at boundaries.
-
understand the theoretical basis for the generation of electromagnetic waves.
-
appreciate the electromagnetic theory under relativistic conditions.
