General information:

Category	Theoretical-methodological
Scientific or art field	Theoretical Electrotechnics
ECTS	6

The aim of this course is to teach students about the principal physical laws related to electromagnetic waves propagation in free space.

Upon successful completion of this course the students are able to calculate electric and magnetic field, as well as power of progressive (incident and reflected) and stationary electromagnetic waves. They are also able to calculate necessary parameters of the environment. Students are educated to communicate with their piers from other branches of science which makes them successful members of multidisciplinary teams.

Fundamental physical laws in Electromagnetics. Maxwell's equations in integral and differential form. Elements of vector analysis. Gauss law and divergence of a vector. Gradient of a scalar function. Ampere's law and curl of a vector. Electric scalar potential. Magnetic vector potential. Retarded potentials. Pointing's theorem. Time harmonic magnetic field. Faraday's law. Mutual and self inductance. Uniform plane transverse electromagnetic waves (TEM). TEM in free space. Field polarization. TEM in a dielectric. Power of a TEM. Good conductors. Skin effect. TEM reflection for Normal incidence. Standing waves. Reflection on multiple dielectrics. TEM reflection for arbitrary incidence. TEM in lossy media.

Inductive method is applied. Starting from specific examples the student learn how to generalize and apply their experience to the unknown problems.
