gorlachThis course of classical electrodynamics is intended for the first-year master students studying the master program "Nanophotonics and metamaterials". The course consists of two logically connected parts: (i) elements of electrodynamics of continuous media; (ii) nanophotonics and metamaterials physics. The aim of the first part of the course is to introduce theoretical methods to describe the propagation of electromagnetic waves in continuous media and periodic structures. The course will also focus on theoretical methods of nanophotonics and approaches to describe metamaterials electromagnetic properties. The second part of the course is devoted to the semi-analytical methods to describe properties of model optical nanostructures. The focus is made on classical description of the interaction of point sources of electromagnetic radiation with optical nanostructures. Emission properties of the sources interacting with such model objects as layered systems, waveguiding structures and nanoparticles are considered; their common features and main differences are discussed. During the course, students are offered to perform simple numerical calculations and make a presentation after studying the research paper related to one of the considered topics

Additional Information

Grading policy:

Final grade is based mostly on the final exam but is also affected by the results of two interim tests. To be admitted to the exam, the student has to pass both interim tests, make the presentation and solve all basic homework problems.
