Content and learning outcomes

Course contents

  • integral representations of electromagnetic fields by means of Green's functions to finite and unbounded regions of arbitrary geometry
  • assumptions, estimates and approximations that are used in integral representations of electromagnetic fields
  • to explicitly connect the field to the sources 
  • methods to solve integral equations in some typical cases
  • equivalence principle for currents to represent electromagnetic fields
  • design of and explanation of the approximations to determine the field from a reflector antenna
  • numerical calculation of current distribution, scattering and/or reflection and transmission for typical cases as: wire antenna, reflector, stratified sphere and dipole over a horizontal surface
  • vector spherical harmonics
  • geometrical optics and physical optics
  • the differential cross-section for different objects
  • dipole above a conducting surface
  • the null field method and properties of its T-matrix
  • derivations of the integral equations in time domain from a given time harmonic integral equation to represent transient processes
  • numerical labs with laboratory report.

Intended learning outcomes

On successful completion of the course, the student should be able to solve and treat problems in parts of the field of wave propagation and scattering, as described in course content below.
For higher grades, the student should furthermore be able to, with progression in both completeness and width, solve problems from the whole course content analytically and numerically and be able to justify calculations in writing and explain simulation results.

Literature and preparations

Specific prerequisites

  • Completed bachelor's thesis work.
  • Electromagnetic Field Theory equivalent to EI1320 or both of EI1220 and EI1222.

Recommended prerequisites

Mathematical Methods in Physics
Theory of Functions
EI2410 Field Theory for Guided Waves, is recommended
Some acquaintance with numerical softwares, like Matlab

Examination and completion

If the course is discontinued, students may request to be examined during the following two academic years.

Grading scale

A, B, C, D, E, FX, F


  • TEN1 - Examination, 7.5 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.

Opportunity to complete the requirements via supplementary examination

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
