TL;DR: Super-oscillations are band-limited functions with the counterintuitive property that they can vary arbitrarily faster than their fastest Fourier component, over arbitrarily long intervals as discussed by the authors, which has implications for information theory and applications to optical vortices, sub-wavelength microscopy and related areas of nanoscience.
Journal ArticleDOI
Superoscillation: from physics to optical applications.
TL;DR: Recent developments in optical ‘superoscillation’ technologies are reviewed, which aim to overcome current limitations in superresolution techniques requiring contact with the observed object, the use of fluorescent labels, or viewing that is restricted to the near-field of a lens.
Journal ArticleDOI
Creation of Sub-diffraction Longitudinally Polarized Spot by Focusing Radially Polarized Light with Binary Phase Lens.
Anping Yu,Gang Chen,Zhihai Zhang,Zhongquan Wen,Luru Dai,Kun Zhang,Senlin Jiang,Zhixiang Wu,Yuyan Li,Changtao Wang,Xiangang Luo +10 more
TL;DR: A planar binary phase lens is proposed and the generation of a longitudinally polarized sub-diffraction focal spot is experimentally demonstrated by focusing radially polarized light.
Journal ArticleDOI
All-dielectric metalens for terahertz wave imaging.

TL;DR: This work proposes a metalens based on an all-dielectric metasurface with a sub-wavelength unit size of 0.39λ for terahertz wave imaging and experimentally demonstrate its performance in focusing and imaging, and demonstrates the reversibility of the metalens for imaging.
Journal ArticleDOI
Super-oscillation focusing lens based on continuous amplitude and binary phase modulation.
TL;DR: Numerical results show that compared with simple binary amplitude modulation, continuous amplitude and phase modulation can greatly improve the super-oscillation focusing performance by increasing the central lobe intensity and the ratio of its energy to the total energy, reducing the sidelobe intensity, and substantially extending the field of view.
