Module Aims
|
- To introduce Maxwell’s equations by continuous superposition of the methods of vector algebra and analysis.
- To introduce the theory of propagation, polarisation, reflection and refraction of light as a direct consequence of Maxwell’s equations.
|
Learning Outcomes
|
- Confidence in use of scalars, vectors and operators acting on them.·
- Confidence in electrostatics, polarization, magnetostatics and magnetization.· Understanding electromagnetic induction, scalar electric potential and vector magnetic potential.·
- Understanding the boundary conditions for the electric and magnetic fields at the plane interface between two different media.·
- Understanding the basics of electromagnetic waves and their polarization.·
- Confidence in using Snell’s law and Fresnel’s formulae.
