## Aim

1. The PhD student shall acquire fundamental knowledge of vector analysis and electromagnetic theory. 2. The PhD student shall acquire a good ability to perform calculations on given problems. 3. The PhD student shall acquire good knowledge of the electromagnetic concepts that are used in electrotechnical applications, e.g., electronics, measurement techniques and electric power techniques.

## Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• be able to explain how electric charge and electric current generate and are affected by electric and magnetic fields.
• be able to use cylindrical coordinates, spherical coordinates, the nabla operator, Stokes´ theorem and Divergence theorem.
• be able to use equations such as Coulomb's law, Biot-Savart law, the law of induction and Maxwell's equations.
• be able to explain concepts such as capacitance, inductance, induction, wave propagation and antenna.

Competences and Skills

For a passing grade the doctoral student must

• be able to analyse an solve basic problems of electrostatics, magnetostatics, quasistationary and general electromagnetic field theory.
• be able to explain how given problems of electromagnetic field theory can be solved.

Judgement and Approach

For a passing grade the doctoral student must be able to describe the strength of and the possibilities of a mathematical model of the type that electromagnetic field theory is an example of.

## Course Contents

Vector analysis, electrostatics, magnetostatics, induction and general time-dependence. Examples of what is treated in the course are divergence, curl, electric fields in vacuum and in materials, capacitors, system of conductors, the image method, Biot-Savart law, force, inductance, the law of induction, Maxwell’s equations, plane waves and antennas.
