Learning Outcome

At the end of the module students understand advanced analytical methods for the solution of electromagnetic field problems. They are able to apply these methods to develop field solutions for modified geometrical and material configurations within the scope of the methods. They understand the relationship and the mutual utilization of mathematical and physical considerations in order to develop field solutions of practical relevance. They understand the importance of analytical concepts for the development of advanced numerical methods in electromagnetics.

Courses, Learning and Teaching Methods and Literature

Learning and Teaching Methods

Learning method:
In addition to the individual methods of the students, consolidated knowledge is aspired by repeated lessons in excercises and tutorials.

Teaching method:
During the lectures students are instructed in a teacher-centered style. The tutorials are held in a student-centered style. The students are expected to give tutorials themselves.

Media

- Presentation slides
- Lecture documents
- Tutorial problems and solutions
- Project work including presentations

Module Exam

Description of exams and course work

The examination is adapted to the learning outcomes and consists of an oral examination of 25 min duration.

In the oral examination, students demonstrate by answering questions under time pressure and without helping material the theoretical knowledge of advanced methods for the solution of electrostatic as well as acoustic and electromagnetic field and wave problems. By describing solution concepts for particular field problems, they demonstrate the understanding of the relevant solution principles.

During the semester, students get the opportunity to participate in voluntary project tasks, in which they can solve different field problems in more detail. These project tasks can be used to improve the final grade.

The final grade consists of the grade of the written exam (100%).
