a. The student is 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/absorbtion of electromagnetic waves).
b. Using force and potential fields, the student will be able to calculate forces acting on charges that are stationary or moving at constant velocity and understand the extension of Maxwell's field theory to describe other physical phenomena, such as gravitational forces or heat flow.
c. The student can calculate fields by means of summation (integration) over sources and can apply integral rules (Gauss's and Stokes's laws) in case of highly symmetric charge or current density distributions.
d. The student is able to design, construct and test a sending antenna for a wireless communication device. The working of a finite elements method (COMSOL) is understood and is applied to calculate electromagnetic radiation (antenna patterns and impedance) to optimize the antenna design.
e. The student understands how electric fields behave inside linear, isotropic materials.
f. The student will have a view on how an international science organization sets its goals, operates and what the engineering issues are related to the domain of Advanced Technology.
g. The student is able to work in a group to gain knowledge in a Problem Based Learning style.



Complex engineering problems – like describing a wing's airflow profile, or an electrical spool's magnetic field – require a mathematical description that employs vectors, a quantity that has both a magnitude and a direction in 3 dimensional space. In this module you will apply vector mathematics in the field of electromagnetism. The behaviour of electric and magnetic fields and their interaction is given by the socalled Maxwell equations. Just four differential equations that describe a wealth of phenomena ranging from big magnets used for medical imaging to the behaviour of light (which is an electromagnetic phenomena) to the interaction between electrons and protons. In a Problem Based Learning style you will solve and discuss successive problems with a small group of students to get insight first in electrostatics, followed by magnetostatics. With magnetostatics you are already able to understand the design of electromagnets, magnetic fields created by a constant current. Electrostatics and magnetostatics are combined in the field of electrodynamics, the mutual interaction of electric and magnetic fields. This forms the basis to understand optical effects and wireless communication. This knowledge will have to be used in the project team for the design and realization of an antenna that works as well as possible within the 100 MHz range. To support the antenna design process the Finite Element Method is introduced. The Finite Element method is used in many engineering areas to evaluate a system described by (partial) differential equations such as fluid motion, thermal behaviour, mechanical stress and bending as well as electromagnetic phenomena. In many engineering problems it is actually a combination of these effects that play a role, for example the cooling of a mechanical structure to prevent thermal expansion with the flow of a cooling fluid. Working with a Finite Element method is not just ask the computer for an answer, as an answer it will give. Therefore this technique can only be used with a proper setup of the problem and the validation of the results.
In the last few years one week of this module was spent on an excursion to CERN to see large magnets of various designs at work. During this visit several problems associated with particle beam dynamics and magnet design and realization are made. Above all this trip provides insight in this international renown institute.
