Content and learning outcomes

Course contents

  • decomposition of the fields and Maxwell's equations in isotropic media
  • analysis of propagating and evanescent TM-, TE- & TEM-modes in metallic hollow waveguides
  • hollow waveguides with rectangular and circular cross-sections
  • application of mode orthogonality at excitation from sources and at energy transport
  • the mode matching method to analyse scattering at discontinuities
  • analysis of attenuation of and coupling between waveguide modes
  • analysis of resonance cavities, orthogonality relations, losses and bandwidth
  • planar dielectric waveguides and optical fibres
  • analysis of the quasi-TEM modes in multiconductor systems

Intended learning outcomes

Having passed the course, the student should be able to

  • demonstrate conceptual understanding and prove general principles of electromagnetic fields in waveguides

in order to be able to use the electromagnetic laws combined with mathematical methods to solve electromagnetic field problems.

To obtain higher grades, the student shall be able to

  • with progression in both completeness and width demonstrate skills in solving specific guided wave problems.

Literature and preparations

Specific prerequisites

  • Completed course at first cycle level in electromagnetic theory equivalent to one of EI1220 and EI1320.
  • Completed course in mathematical methods in physics, containing vector calculus, separation of variables and orthogonal functions equivalent to SI1200 Mathematical Methods of Physics.

Recommended prerequisites

Basic courses in electromagnetic theory. Course in mathematical methods in physics and complex analysis are recommended.

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


  • PROA - Project, 1.5 credits, grading scale: A, B, C, D, E, FX, F
  • TENA - Written exam, 6.0 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.
