Learning Outcomes
Upon the successful completion of the course, the students will be able to comprehend and assimilate the concepts of the electromagnetic induction, the behavior of magnetic materials, the electromagnetic (time varying) field and the system of Maxwell equations, the properties and types of uniform plane waves, both for free space propagation and incidence onto plane interface between two homogeneous media. Specifically, the students will have acquired the following skills: - To comprehend and interpret the physical meaning of all the related field quantities and concepts in practical and applied structures concerning the development process of the induced electromotive force and the mutual flux, self and mutual inductance. - To solve magnetic circuits with linear and nonlinear magnetic permeability. - To conduct calculation by means of Maxwell's equations, the boundary conditions and the Poynting theorem, obtaining thus the necessary background to treat problems with time-varying electromagnetic fields. - To solve problems uniform plane waves, to work with phasors for electromagnetic fields with harmonic time variation. To discern and mathematically describe the polarization of a uniform plane wave and handle propagation problems in perfectly (and non) electric conductors. - To solve simple vertical/oblique incidence problems with parallel/perpendicular polarization for various media and calculate the necessary reflection and refraction coefficients.
