6. Tinkering with Light at the Nanoscale using Plasmonic Metasurfaces and Antennas: From Fano to Function
Sammanfattning : Surface plasmons are charge density oscillations that can couple strongly to light and be excited in, for instance, thin metal films and metal nanoparticles. The plasmonic excitation squeezes the light down to nanometric length scales, far smaller than the wavelength of the light. LÄS MER
7. Simulations of directionality effects and optical forces in plasmonic nanostructures
Sammanfattning : With the rapid development of nanoscience and nanotechnology, surface plasmonics based on metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for optical and sensor applications. At the nanoscale, the physical and chemical properties of metal particles, especially their optical properties, strongly depend on size and shape, as well as on the surrounding media and structures.

8. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing
Sammanfattning : The interaction of light with sub-wavelength noble metal nanoparticles and nanostructures has developed into one of the most vibrant themes of nanoscience during the past decade. The optical properties of metal nanoparticles are dominated by so-called nanoparticle plasmons or localized surface plasmon resonances (LSPR). LÄS MER
9. Plasmonics with a Twist: from Single Particles to Metasurfaces
Sammanfattning : Nanophotonics deals with how electromagnetic fields can be confined and squeezed to orders of dimensions below the light wavelength. Plasmonics, one of the fields of nanophotonics, study collective free electron oscillations driven by light in metallic nanostructures and interfaces. LÄS MER
10. Optical properties of nanometer disks, holes and rings prepared by colloidal lithography
Sammanfattning : The optical properties of nanostructures prepared by colloidal lithography are studied. Colloidal lithography is a fabrication approach based on a self-assembling pattern definition. An electrostatically self-assembled array of nanoparticles is used as a mask and combined with etching or deposition processes. LÄS MER
