11. Alloy Plasmonics - Fundamentals and Applications
Sammanfattning : Alloys have for a long time been important in the development of our society; from the Bronze Age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, alloys have lately been proposed as a new paradigm in nanophotonics, to tailor optical properties of nanomaterials that find applications within telecommunication, sensing, or biotechnology.

12. 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
13. Designer magnetoplasmonics for adaptive nano-optics
Sammanfattning : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.

15. Theoretical studies of collective electronic excitations in low-dimensional structures
Sammanfattning : During the past decade, nanoplasmonics and nanophotonicshas emerged as a new branch of nanosciences with many novelapplications. Central in this development is the localized surface plasmon resonance (LSPR) tunable by the sizes and shapes at nanometer scale. LÄS MER
