You will be able to use Maxwell's classical theory of electromagnetism to describe and evaluate electromagnetic fields and waves produced by electric charges, which are either stationary (producing static electric fields), moving at constant velocity (producing static magnetic fields) or accelerating (leading to emission of electromagnetic waves).
Using force- and potential fields, you will be able to calculate forces acting on charges that are stationary or moving at constant velocity.
You will also be able to understand and model how accelerating charges in antennas may be used to emit (send) and absorb (receive) electromagnetic waves (information).
You will be able to use Maxwell's field theory to describe other physical phenomena, such as gravitational forces or heat flow.
With respect to field calculations, you will be able to:
calculate electric- and magnetic fields for highly symmetric charge- or current density distributions using integral rules (Gauss's- and Stokes's laws);
calculate these fields by means of summation (integration) over sources, which can be used if the location of the charges and/or currents is known;
You will have designed, constructed and tested a sending antenna for a wireless communication device. You will have used the method of moments (NEC2) to calculate electromagnetic radiation (antenna patterns and impedance);
You will have limited knowledge on electric fields inside linear, isotropic materials.
Fields: vector- and scalar fields, gradient, divergence, rotation, flux and circulation of vector fields, Theorems of Gauss and Stokes;
Waves: the wave equation and its solutions;
Electrostatics: electric field, Coulomb's Law, superposition of fields from charges and charge distributions, Gauss's Law, electrostatic potential, dipole, equations of Laplace and Poisson, dielectrics, electrostatic analogues;
Magnetostatics: magnetic field, Ampere's Law, Law of Biot and Savart, vector potential, current and current density, magnetic dipole, energy density,.
Electrodynamics: induction, plane waves in free space, radiation, interference, polarization, resonance in cavities, waveguides, transmission lines, phase and group velocity, pointing vector, reflection and diffraction.
