The title of thesis “Resonant scattering particles: Morphological characteristics of plasmonic and dielectric resonances on spherical, superquadric and polyhedral inclusions”

The dissertation discusses the electromagnetic scattering of single subwavelength nanoparticles and nanoantennas and their morphological effects to the overall scattering response. In particular, the energy localization via plasmonic or dielectric resonances has been studied for a number of shapes, such as spheres, spherical shells, tetrahedra, hexahedra, octahedra, dodecahedra, and icosahedra. The results were extracted via analytical methodologies (sphere) or with the aid of computational techniques (non-spherical particles), elucidating the shape effects to the overall scattering response. Understanding the single-particle response is of paramount importance for applications with enhanced or novel energy control/harvesting functionalities within the areas of RF engineering, material science, applied physics, optics, and photonics.
