Objectives

At the end of this module you should be able to:
- state Maxwell's equations and discuss their derivation from the physical laws of electromagnetism, in vacuo and in dielectric and magnetic media;
- describe the nature and properties of electromagnetic waves;
- evaluate the nature of polarized EM waves and their reflection and refraction by boundaries;
- carry out standard phasor analyses of basic problems in interference/diffraction and AC circuits.

Skills outcomes
Ability to comprehend everyday electromagnetic phenomena in the context of classical field theory - transferable to Geophysics, Engineering, Medical Physics, etc.Ability to comprehend everyday electromagnetic phenomena in the context of classical field theory - transferable to Geophysics, Engineering, Medical Physics, etc.
