General goals
After the course the student shall from a description of a situation that leads to an electromagnetic field problems be able to
- use their conceptual understanding of the electromagnetic laws in order to qualitatively describe the behavior of the solution to the problem
- use their ability to manage the electromagnetic laws to, in simple situations, set up a computational model and perform the necessary calculations: select appropriate methods; make appropriate approximations; plausibility assess the results
Concrete goals
- calculate the forces and torques by conservation laws for energy, momentum and angular momentum
- analyze the polarization state of an electromagnetic wave
- analyze refraction and interference of electromagnetic waves by reflection from interfaces
- explain the basic concepts of transmission lines and calculate currents and voltages along a transmission line
- use the Smith chart for solving matching problems
- analyze wave propagation in rectangular waveguides
- distinguish between near-field and far-field properties
- calculate the radiation field from straight wire antennas with given current distributions
- calculate the radiation field from antenna arrays without coupling between the elements
- explain the concepts of radiation pattern and radiation resistance
- describe the concepts of directivity, antenna gain and beamwidth

Examination and completion
Grading scale
A, B, C, D, E, FX, F
Examination
- TEN1 - Written Exam, 4.5 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
If the course is discontinued, students may request to be examined during the following two academic years.
Other requirements for final grade
Passed in all examination moments.
