Närmare beskrivning av kursens innehåll (gäller denna kursomgång): 

The interdisciplinary science of metamaterials and nanophotonics deals with electromagnetic devices and components whose characteristic dimensions are smaller or of the same order (as in photonic crystals) as the wavelength of radiation which they control. While for the use at microwave and radio frequencies we have a basically complete set of components (waveguides, passive, active, and nonreciprocal elements) as well as means to integrate them into extremely small devices, at the optical frequencies only the intermediate regime where the characteristic sizes are comparable with the wavelength is well studied and developed: the photonic crystal technique is quite mature at this time. Any progress towards sub-micron integration of photonic devices is impossible without advances in metamaterials and nanophotonics, which is the subject of this course.
