Course organization:
The course consists of 36 hours of lectures in connection to 44 hours of problem solving sessions and 6 hours of computer simulations.

Course content:
Electrostatics: Electric Field Intensity, Coulomb's law, Potential, Gauss's law, Poisson's and Laplace's Equations, Capacitance, Dielectrics, Electric Dipole, Polarisation, Electrostatic Energy and Forces, Method of Images. Steady Electric Currents: Current Density, Equation of Continuity, Resistance, Joule's law. Magnetostatics: Magnetic Flux Density, Biot-Savart law, Ampere's Circuital law, Vector Magnetic Potential, Magnetic Materials, Magnetic Circuits, Magnetic Dipole, Magnetisation, Magnetostatic Energy and Forces, Motion of Charged Particles in Electromagnetic Fields. Time-Varying Electromagnetic Fields: Induction, Faraday's law, Inductance, Electromotive Force, Displacement Current Density, Skin Effect, Electromagnetic Waves, Poynting Vector. Snell's laws of reflection and refraction, and Fresnel's formulas are derived from electromagnetics. Certain applications of electromagnetics on waveguides. The different parts of the course are presented as specific applications of Maxwell's equations.
