Description for 2019/20

Much of our modern-day lives are governed by devices and technologies that rely on an understanding of the behaviour of electromagnetic fields and waves in a variety of situations and media.
This module provides a classical description of electromagnetic waves and electromagnetic fields, based upon Maxwell's equations. Beginning with Maxwell's equations, the properties of electromagnetic waves in vacuum and then in conducting and non-conducting media are explored. The behaviour of electromagnetic fields at the interfaces between media is described and we see that simple physics such as the laws of reflection and refraction are basic consequences of Maxwell's equations. The module acts as an introduction to more advanced topics in physics through the concepts of electromagnetic potentials, gauge transformations, the generation of electromagnetic waves and the deep connection between electromagnetism and relativity. The course has a significant mathematical content, particularly in dealing with the properties of vector and scalar fields in three dimensions and in several coordinate systems, using the methods of vector calculus.
Students will gain an appreciation of the beauty of Maxwell's universe and how simple sets of laws and equations can lead to myriad complex, yet often highly useful, behaviours that find applications in many areas of physics and astrophysics - from mobile communications devices to gamma ray bursts. They will learn how to deal with complex three-dimensional problems, and how to choose appropriate numerical or analytical methods to solve them.
This is a core Physics/Astrophysics module, dealing with a number of topics that are considered a compulsory part of an Institute-of-Physics-accredited degree course. A successful completion of level 4 and 5 Physics or Astrophysics is the only entry requirement.

Aims
To develop an understanding, at the undergraduate level, of electromagnetism and its applications in Physics, the nature of electromagnetic waves in vacuum and various media and of magnetism in solids. Describing the universe and the world around them.
