Introduction
Nanooptics, nanofotonics and plasmonics. History of plasmonics. Research topics in plasmonics. Applicatons of plasmonics: biosensors, plasmonic antennas. Numerical simulations.
Lecture I – Electrodynamics of materials
Propagation of electromagnetic waves in metals: dielectric function and complex conductivity of materials, complex index of refraction, Kramers-Kronig relations. Examples of polariton dispersion relations: bulk photon polaritons, bulk plasmon polaritons.
Lecture II – Dielectric function of metals
Drude model. Dielectric function of real metals and interband transitions. Drude-Lorentz model, examples: gold and silver.
Lecture III – Surface plasmon polaritons (SPP)
Propagation of electromagnetic waves at metal-dielectric interfaces: Surface plasmon polaritons (SPP) – single interface, multilayer systems. Application of SPP – planar waveguides, sensors . Thin film optics and SSP.
Lecture IV – Excitation, detection and imaging of SPP
Excitation of SSP by fast electrons. Excitation and detection of SSP by light (ATR, SNOM)
Lecture V – Localized plasmon polaritons (LSP)
Interaction of em wave with nanoparticles: Mie theory of scattering and absorption of electromagnetic radiation by a sphere. Quasi-static approximation. Scattering, absorption and exctiction cross-section. Approximation to more general object shapes (including apertures and voids). Mmethods of observation of LSP, coupling between LSP. Application of LSP – resonant plasmonic antennas.
Final lecture – new and advanced topics
Fano resonance: dimers, hybridisations, dark and bright modes, Plasmon Induced Transparency, an exaple: Nanoshell and Matryoshka-nanoshell
Plasmonic nanoantennas: manufacturing of nanoantennas, mapping nanoantennas, local enhancement electromagnetic field in vicinity of metallic particles or tips and antennas – surface enhanced Raman spectroscopy (SERS) and tips enhanced Raman spectroscopy (TERS), respectively, luminiscence induced by a metallic tip (STL), lithography.
