**Course:** Photonic Nanostructures 1

**Department/Abbreviation:** SLO/BFN1

**Year:** 2021

**Guarantee:** 'Ing. Jaromír Křepelka, CSc.', 'prof. RNDr. Jan Peřina, Ph.D.'

**Annotation:** The aim is to recall the propagation of electromagnetic waves solving Maxwell equations, to state basic physical properties of interaction between radiation and matter and to describe linear phenomena in layered systems and linear properties of optical waveguides.

**Course review:**

- Description of electromagnetic field, Maxwell equations and their solutions, boundary conditions, polarization, coherence

- Linear phenomena in layered media: periodic layered media, Broch waves, band structure, selected applications, generalization of the description for inhomogeneous layers, WKB method
- Linear optics of thin layers, properties of thin layers, methods of production of thin layers and their checking, propagation of electromagnetic field through isotropic inhomogeneous medium, matrix description of the systems of thin layers, transformation of the field and transmission of energy in the systems of thin layers, principle of reversibility
- Examples: interface of two media, one thin layer, one thick layer, systems of thin and thick layers, layer in partially coherent light, field inside the system of thin layers, symmetric systems, periodic structures, antireflective structures, MacNeill polarizer, Fabry-Perot filter, basics of evaluation of ellipsometric measurements
