Aim
The purpose of the course is to give a coherent description of basic theory as well as of applications of electromagnetic theory. Emphasis will be on physical insight coupled to the use of mathematical models. The course is also intended to throw light upon the numerous applications of electromagnetic field theory such as optics, electronics, communication technology, chemistry, and biology.

Knowledge and understanding
For a passing grade the student must

• be able to explain how electric charge and electric current generate and are affected by electric and magnetic fields

• be able to describe the electromagnetic properties of different materials

• be able to apply the Maxwell equations to simple electrostatic, magnetostatic and electrodynamic problems

• be able to understand basic propagation and generation of electromagnetic waves

Skills and abilities
For a passing grade the student must

• show ability to, from an engineering point of view, assess electromagnetic problems, make relevant approximations and chose suitable method of solution

• show ability to analyze and model electromagnetic problems, to interpret and present the results

Judgement and approach
For a passing grade the student must

• be able to explain the strength and the generality of a field theoretical description of physical phenomena

• understand that electromagnetism is the foundation to electronics, optics and radio communications
