Journal of Modern Optics, 1-10.0950-0340https://hdl.handle.net/20.500.12939/3180Diffraction of a spherical wave through various types of 2D aperiodic hollow masks is investigated computationally. Unlike a periodic transmissive grating, an aperiodic hollow mask can focus light into a hotspot with sub-wavelength diameter. In this work, several types of 2D aperiodic hollow masks are investigated in the framework of sub-diffraction focusing of light and generating superoscillations at the hotspot region.eninfo:eu-repo/semantics/closedAccessAperiodic StructuresDiffractionSub-DiffractionSuperoscillationSuperresolutionArticle1102-s2.0-85144523049Q3WOS:000900652300001Q4
