Electrodynamics and Special Theory of Relativity (FSI-TDE)

Academic year 2020/2021
Supervisor: prof. RNDr. Petr Dub, CSc.  
Supervising institute: ÚFI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course objective is provide students with basic ideas and methods of classical electrodynamics and enable them to be capable of applying these basics to physical systems in order to explain and predict the behaviour of such systems.
Learning outcomes and competences:
The knowledge of principles of classical electrodynamics and ability of applying them to physical systems in order to explain and predict the behaviour of such systems.
Prerequisites:
Knowledge of electromagnetism on the level defined by the textbook HALLIDAY, D. - RESNICK, R. - WALKER, J.: Fundamentals of Physics. J. Wiley and Sons.
MATHEMATICS: Basics of vector analysis.

Links to other subjects:
compulsory prerequisite: General Physics II (Electricity and Magnetism) [TF2]
Course contents:
The course represents the second part of the basic course of theoretical physics. It is concerned with principles of the electromagnetic field theory and the description using Maxwell's equations. Conservation laws of energy and of quantity of motion are derived, field potentials are introduced and electrostatic, magnetostatic and quasistationary fields are described. A great attention is paid to spreading of electromagnetic waves in diverse environments and also to the behaviour of the field at the interface between two environments. At the end of the course the motion of charged particles in electromagnetic fields, principles of the special theory of relativity and invariance of Maxwell equations under the Lorentz transformation are explained.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
The exam is combined (written and oral).
Controlled participation in lessons:
Attendance at seminars is required and recorded by the tutor. Missed seminars have to be compensated.
