Abstract
Photonic Hooks (PHs) are non-evanescent light beams with a highly concentrated curved optical field. Since their discovery, PHs always have one single inflection point and thus have a hook-like structure. In this work, a new type of PHs with two inflection points and S-shaped structures were reported for the first time. We theoretically studied the effects of various physical parameters on the generation of S-shaped Photonic Hook (S-PH). The S-PH may have potential applications in super-resolution imaging, subwavelength micromachining, particle and cell manipulation, etc.
