Electromagnetics (2025)

Cancelled!

Welcome to Electromagnetics

Description: This course should provide the PhD candidates in the Wireless Communications program the necessary background on the physical aspects of radiowave communication. The motivation follows the well-known fact that students in this program come from various backgrounds, often specialized in communication protocols and information theory, but lacking the necessary physical insight into electromagnetic fields, antennas and radiowave propagation. For the rest of the participants, this course should give a recapitulation of the previously acquired knowledge and extending it to meet the needs of their dissertation, as many of them will need to design an antenna and/or carry out electromagnetic simulations in their projects. Both basic and advanced aspects of electromagnetic theory will be covered, together with numerical methods for solving electromagnetic fields at high frequencies. The course consists of total 12 hours of lectures divided in 4 days plus a mini-project of approx. 1 month duration supervised and evaluated by the lecturer. Criteria for assessment are attendance of the lectures and evaluation of the mini-project.

Important information concerning PhD courses: 

There is a no-show fee of DKK 3,000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before the start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start of the course.

We cannot ensure any seats before the deadline for enrolment, all participants will be informed after the deadline, approximately 3 weeks before the start of the course. 

For inquiries regarding registration, cancellation or waiting list, please contact the PhD administration at phdcourses@adm.aau.dk When contacting us please state the course title and course period. Thank you.
