Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After successful completion of this course, the student can:

  • Explain the fields and modes inside waveguides and calculate wave propagation parameters.
  • Select the appropriate waveguide for a given application.
  • Understand the working principles of direct detection.
  • Explain how THz radiation is generated and detected via photonic means.
  • Understand how the imaging applications benefit from THz technology and how application requirements drive technology development.
  • Explain some basic THz electronic devices.
  • Explain the operation of some basic THz antennas and quasi-optical components.
  • Explain the relevant measurement techniques at THz frequencies.
