Enlargement of knowledge of electromagnetic field (Maxwell equations, solutions in various medias, solution for harmonic response using phasors, description of medium from the radiowave propagation point of view.) Propagation along long lines (line matching, Smith chart). Propagation of radio-waves in space, multipath propagation, reflections and scattering of electromagnetic waves at boundary, real atmosphere influence on attenuation and phase delay of propagating radio wave, influence of terrain obstacles, Fresnel zones. Basic antenna types, properties of antennas from the technical practice point of view. Transformation of time and frequency domain (Fourier and Laplace transform), periodical signals, signal spectra, harmonic components, transient states. Determination of the time domain response from the response in the frequency domain for linear circuits, non periodical and random signals, crosstalks and shielding. Ultra wide band (UWB) and narrow band systems. Digital circuits, spectrum analyzers. Radiated emissions and susceptibility. Guided emission and susceptibility.

Learning outcomes
|
This topic should deepen the student's knowledge concerning electromagnetic compatibility (EMC) especially from the electronic system point of view. Enlargement of theoretical knowledge of electromagnetic fields, wave propagation through space and lines are emphasised.
The student is able to solve more sophisticated tasks of the interference signal transmission (through space as well as line) and derive pertinent formulas and work with spectral analysis. Student takes bearing in the EMC field, differentiates interference sources as well as various ways of interference transmissions, he is able to suggest solutions to minimise the interferences. The student as also able to use the basic measurement methods of interference signal, he knows pertinent regulations.
