The author also develops a unique practical simulation framework which is used to confirm the results. The development of innovative photonic devices and metamaterials with tailor-made functionalities depends critically on our capability to characterize them and understand the underlying light-matter interactions. Thus, imaging all components of the electromagnetic light field at nanoscale resolution is of paramount importance in this area. This challenge is answered by demonstrating experimentally that a hollow-pyramid aperture probe SNOM can directly image the horizontal magnetic field of light in simple plasmonic antennas – rod, disk and ring. These results are confirmed by numerical simulations, showing that the probe can be approximated, to first order, by a magnetic point-dipole source. This approximation substantially reduces the simulation time and complexity and facilitates the otherwise controversial interpretation of near-field images. The validated technique is used to study complex plasmonic antennas and to explore new opportunities for their engineering and characterization.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053LasersPhotonicsOptical materialsElectronic materialsNanoscale scienceNanoscienceNanostructuresNanotechnologyOptics, Lasers, Photonics, Optical Deviceshttps://scigraph.springernature.com/ontologies/product-market-codes/P31030Optical and Electronic Materialshttps://scigraph.springernature.com/ontologies/product-market-codes/Z12000Nanoscale Science and Technologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P25140Nanotechnologyhttps://scigraph.springernature.com/ontologies/product-market-codes/Z14000Lasers.Photonics.Optical materials.Electronic materials.Nanoscale science.Nanoscience.Nanostructures.Nanotechnology.Optics, Lasers, Photonics, Optical Devices.Optical and Electronic Materials.Nanoscale Science and Technology.Nanotechnology.530Denkova Denitzaauthttp://id.loc.gov/vocabulary/relators/aut808442BOOK9910254615903321Optical Characterization of Plasmonic Nanostructures: Near-Field Imaging of the Magnetic Field of Light1811523UNINA
