This crash course in electromagnetics aims to give engineering students with a BSc a minimum of prerequisites to follow a 2-year master program in Electronic systems design or Electric power engineering at NTNU. It is not necessary to sign up for the course. The teaching will consist of lectures and voluntary exercises. There will be no tests or exam.

You may also find lectures covering basic electromagnetism online, e.g. TFE4120 Elektromagnetisme (NTNU, 2013) (Norwegian) and Electromagnetism (Yale, 2010) (English).

 

Teacher:
Anyuan Chen, e-mail:anyuan.chen*snabela*ntnu.no. Office: E421 (electro building).

Assistant:
Ine Jernelv, e-mail:ine.jernelv*snabela*ntnu.no. Office: B419 (electro building).

Lectures:
It will be given a total of 6-7 lectures and 6 exercises in this course. Solution proposals will be posted shortly after each lecture. Each lecture will last 3 hours. The first lecture is monday August 6th. A provisional time table is found below. Please notify me if you find typos or errors in the lecture notes or exercises!

Help with Exercises
There are no scheduled exercise hours in this course. Anyuan will go through some of the exercises at the end of each lecture, and you are otherwise advised to work with them on your own time. 
Ine is available if you have any questions regarding the exercises. Her office is open from 12:00-13:00 and 16:00-17:00 each day until Thursday 16/8 (starting from Tuesday 7/8).

Syllabus (suggested):

Lecture notes (in English) will be posted for each lecture. Please notify Anyuan if you find typos or errors in the lecture notes!

Norwegian students: Prof. Johannes Skaar har skrevet et kompendium til bruk i kurset TFE4120. Dette er gratis for studenter og anbefales som litteratur i dette kurset. Du finner kompendiet her (in Norwegian only).

Tilleggslitteratur: Field and Wave Electromagnetics (Cheng) (elektronikkstudenter, brukes i "TFE4130: Bølgeforplantning") eller Electromagnetics (B. M. Notaros) (elkraftstudenter).

International students: Electromagnetics (B. M. Notaros).
