Lectures and tutorials at our Institute

Lecture

After finishing the course, students will be able to present and explain the basics of electromagnetic field theorie. They can differentiate between integrated and local representation and argue for the more general aplicability of the local representation in form of differential equations. They are aware of the prerequisites for the simplification of equations and have the tools to judge their aplicability for given problems. They can calculate the fields resulting from given sources and sinks. They can present the reaction of matter to an electromagnetic field and derive the macroscopic maxwell equations from their microscopic counterparts. They can apply those equations inside matter and on surface areas. They can calculate the propagation of a plane wave and it's interaction with matter in simple geometries. They can find strategies to solve elementary problems.

Practice

Contacts

The practices for the lecture Grundlagen der elektromagnetischen Feldtheorie are supervised by Björn Neubauer, Lukas Oppermann and Altan Akar.

Material is provided on Stud.IP at the lecture in the section 'Dateien'.

Exam

Writen exam of 120 minutes or oral exam of 30 minutes.

Lecture

Students will be able analyse basic electronic devices using field theory and abstract them into a simpler form. They can choose and execute strategies for solving for example energetic problems, the poynting-theorem or temporal and spacial variable fields.

Contents Of Lecture

Quantitative description of radiation phenomena by specific numeric methods - Theoretical concepts of established methods (FE, FD, MoM) and newer approaches (e.g. wavelets) - Criteria for bandwith and complexity of boundary conditions - Usabillity of methods - Practical examples from EMC and atenna develpoment.

Practice

Programming practice in a CIP-computerroom

The practice will be conducted as programming practice in a CIP- computerroom. Radiationproblems will be evaluated using the programms CONCEPT II, based on the Method of Moments, and Meep, based on the Finite Difference Time Domain.

In particular advantages and disadvantages of both methods will be evaluated. Additionaly the possibilities of both programms will become apparent.

Links:

• Meep is developed by MIT (Massachusetts Institute of Technology).
• Infos on CONCEPT II can be found on the homepage of the TU Harburg.

Exam

Times of oral exams are available at the institute blackboard.

Duration: About 30 minutes.

Appointments are availiable by request.
