Planned learning activities and teaching methods

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 assessment of a student is made upon his performance in practice and quality of a discussion on topics selected at the examination (lecture notes allowed at preparation).

Language of instruction

English

Work placements

Not applicable.

Aims

The goal is to give an overview of the methods providing the application of electromagnetic signals in the structures with dimensions below diffraction limit, especially on plasmonics as the major part of nanophotonics.

Specification of controlled education, way of implementation and compensation for absences

The presence of students at practice is obligatory and is monitored by the tutor. The way how to compensate missed practice lessons will be determined by the tutor depending on the extent and content of the missed lessons.
