Abstract (Summary)

In this thesis, we study the optical response of planar spectrometers based on disorder scatterers, composite dielectric nanoparticles with plasmonic shell, and all-dielectric magneto-optical shape-modified metasurfaces. Therefore, we employ both Mie and multiple scattering theory as well as a discontinuous Galerkin time-domain method based on finite elements for the numerical computation of the electromagnetic fields. Specifically, we present a theoretical design study for obtaining random spectrometers with high spectral resolution. Furthermore, we provide an alternative strategy to achieve preferentially high backscattering by studying the optical properties of composite nanoparticles. Finally, we present enhanced Faraday rotation along with high transmittance in alldielectric magneto-optical metasurfaces composed of shape-modified nanodisks.
