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.
