Learning outcomes of the course unit

The subject graduate will acquire the necessary basic knowledge in this area to study subjects related to the design of electrical and electronic structures, communication systems and other technologies.

Prerequisites

Knowledge at the level of secondary education and compulsory subjects completed by the student in the first year of study at FEEC are required. Emphasis is placed on knowledge of basic statistical methods, theoretical electrical engineering, signal processing and analogue technology. The work in the laboratory is subject to the valid qualification of an "educated worker" according to Vyhl. 50/1978 Coll., which students must obtain before starting lessons. Information on this qualification is provided in the Dean's Directive Familiarising students with safety regulations.

Aims

Introduce students with the physical nature of selected electromagnetic phenomena significant in terms of further use in electrical engineering and with their description using Maxwell equations. The student is to acquire the capacity to quantitatively estimate the manifestations of electromagnetism (forces, energy, losses, etc.).), can solve simple tasks analytically, understands the principles of numerical methods used in field simulators, can use results of simulations (field knowledge) to determine parameters such as electrical resistance, inductivity, electrical capacity of the specified arrangement.
