Description

The aim of the course is to develop a knowledge and understanding of a wide range of electromagnetic wave phenomena by solving, with appropriate physical insight, Maxwell's equations in particular circumstances, e.g. dielectrics, conducting media, waveguides, antenna behaviour, The module will also introduce radiation and radiating systems and study the dynamics of charged particles in electromagnetic fields.

Learning Outcomes

1. State and manipulate Maxwell's and Fresnel's equations.
2. Solve Maxwell's equations to find plane wave solutions in vacuum, isotropic dielectrics, conducting media, planar, rectangular and cylindrical waveguides.
3. Calculate the electromagnetic radiation from localised charges which move arbitrarily in time and space, taking into account retardation effects and account for the underlying approximations and assumptions.
4. Calculate the scattering of electromagnetic radiation by atoms and molecules. Explain the physics of Thompson and Rayleigh scattering.
5. Use the techniques of electromagnetism and vector analysis to solve numerical problems.
6. The student will have an awareness of ethical issues in relation to plagiarism
