Plasmonics 1100-3IN`Pla

Introduction: plasmonic effects in ancient art.

Fundamentals: Maxwell equations. material equations, optical properties of metals, evanescent waves, dispersion models of Lorentz and Drude. Surface plasmon-polariton wave. Metal-insulator-metal (MIM) and insulator-metal-insulator (IMI) structures.
Generation of plasmons. Polarization of light: linear,circular, radial, azimuthal. Numerical method: finite-differnce time-domain (FDTD) and transfer matrix (TMM) methods.

Phenomena: Light transmission through metal-dielctric multilayers. Superresolution in classical optical systems and plasmonic ones. Metamaterials.

Applications: Plasmonic lenses of a single metal layer (Veselago, Pendry, Zhang, Wróbel) and several layers of metal and dielectric (Scalora, Blaikie, Kotyński). Electromagnetic wavefront shaping using metal-dielctric multilayers. Probes for SNOM. Probes for scanning near-field magnetic microscope. Photonic crystals. Filters with asymmetric transmission.

Outlook: plasmonics in photovoltaics. Plasmonic sensors.

Prerequisites (description)

Plasmonics: fundamentals, phenomena, present applications, persp-ectives. William L. Barnes, one of the creators of plasmonics, wrote in the introduction to Maier's book Plasmonics: "You just have Maxwell's equations, some material properties and some boundary conditions." The key point is that we can connect metal nanostructures with dielectrics to achieve unusual properties: concentration and guiding light in subwavelength structures. This is possible due to new devices to fabricate and characterize nanostructures.
