Generation of Photonic Hooks under Point-Source Illumination from Patchy Microcylinders
Photonic hook (PH) is a new type of non-evanescent light beam with subwavelength curved structures.It has shown promising applications in super-resolution imaging and has the potential to be used in micromachining, optical trapping, etc.PHs are generally produced by illuminating mesoscale asymmetric particles with optical plane waves.In this work,
