Learning outcomes of the course unit

After successfully passing the course, a student understands basic concepts of EMC with an emphasis on their underlying physics and mathematical description. Furthermore, the student is able to (a) apply the Laplace transform to the analysis of causal signals; (b) derive the shielding efficiency of planar shields; (c) derive the characteristic impedance of simple transmission lines; (d) derive integral equations for EM scattering analysis; (e) describe EM radiation from fundamental antennas; (f) apply the Lorentz reciprocity theorem to systems EM susceptibility analysis.

Prerequisites

Linear algebra; complex variable calculus; integral transformations; fundamentals of EM-field, antenna and transmission-line theory.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Techning methods include seminars covering lectures, and practical team project work. Course is taking advantage of e-learning (Moodle) system.
