Course information

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.
