Anotation:

This course presents fundamentals of electromagnetic field theory and its applications. Analysis methods proper for static, stationary as well as dynamic fields and waves in free space and on basic transmission lines are presented as well. This course provides students with physics - based wiev on studied effects, which is applied then on engineering problems. At the end of the course, all effects should not only be described, but quantified as well. Basic knowledge and insight into communication devices, systems and techniques is provided, applicable not only to systems currently taught in other courses, but to future systems as well.

Study targets:

Basic knowledge and insight into communication devices, systems and techniques.

Course outlines:

 1 Basic principles, field sources, charge(s) and current(s). 2 Field caused by charges, Laplace and Poisson equation, polarisation, capacity. 3 Magnetic field caused by steady current. Self and mutual inductance. 4 Magnetic circuit analysis, ferromagnetics. 5 Induction law. Nonstationary fields. Maxwell equations, practical explanation. 6 Energy and force contained in/caused by electromagnetic field 7 Electromagnetic wave, wave equation and its solution in the case of planar harmonic wave 8 Planar waves in lossy media, waves at planar interfaces, Snell's law 9 Poynting theorem. Fields and waves in conductive media. 10 Analytic and numeric analysis and its applications 11 Guided waves, transmission lines and its parameters, transmission, reflection, impedance 12 Smith chart, parameters on display and its application in impedance matching 13 TEM transmission lines, coaxial, Lecher ad other line types 14 Waveguide with rectangular crossection, parameters, modes, resonators.
