1. 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.

2. Micro- and Nano-structured Metal Films for Optoelectronic Devices
Sammanfattning : Two types of micro and nanostructures of metal-dielectric films have been explored with the intention of improving optoelectronic devices.The first part of the thesis concerns the design, fabrication and characterization of a metallic photonic crystal (mPhC). LÄS MER
3. Reliable hp finite element computations of scattering resonances in nano optics
Sammanfattning : Eigenfrequencies are commonly studied in wave propagation problems, as they are important in the analysis of closed cavities such as a microwave oven. For open systems, energy leaks into infinity and therefore scattering resonances are used instead of eigenfrequencies. LÄS MER
