Learning outcomes
After taking this module students should be able to:
-
describe the fundamental theoretical basis for electromagnetic waves.
-
describe the propagation of plane electromagnetic waves in both free space and media and their behaviour at boundaries.
-
explain the theoretical basis for the generation of electromagnetic waves.
-
appreciate the electromagnetic theory under conditions of special relativity.
Brief description
This module develops Maxwell's equations and their application to electromagnetic waves. The full theory of transmission, reflection, dispersion and absorption of electromagnetic waves is developed for free-space, conductors and dielectrics. The theoretical basis of the generation of electromagnetic radiation is presented and the laws of electromagnetism are discussed in relation to the special theory of relativity.
Content
Electromagnetic Waves: Maxwell's equations, electromagnetic waves in free space, energy and Poynting vector, dispersion, absorption of plane waves in conductors, skin effect, reflection and transmission, dielectric and conducting boudaries.
Waveguides: Propagation between conducting plates, rectangular waveguides, cavities.
Generation of electromagnetic waves: Retarded potentials, Hertzian dipole, antennas, scattering.
Electromagnetism and Special Relativity: Charges and fields, Four-vectors, Maxwell's equations.
