Intended learning outcomes

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

  • 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 mode decomposition in rectangular and circular hollow waveguides, and in planar dielectric waveguides
  • determine resonance frequencies and losses in cavity resonators
  • 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

Course main content

  • plane waves: reflection and transmission at oblique incidence; critical angle; Brewsterangle
  • transmission line theory: distributed parameters, characteristic impedance; matching; Smith chart
  • rectangular and circular waveguides; dielectric waveguides; cavity resonators
  • fields from general source distributions
  • basics of antenna arrays and wire antennas; radiation pattern; radiation resistance; antenna demonstration
