Popis:	Photonic hooks (PHs) are non-evanescent light beams with a highly concentrated curved optical fields. 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 (S-PHs) were reported for the first time. We theoretically studied the effects of various physical parameters on the generation of S-PHs. Furthermore, we showed that decorating particles with multiple patches can significantly enhance the curvature and length of the S-PHs. The S-PHs may have potential applications in super-resolution imaging, sub-wavelength micromachining, particle and cell manipulation, etc. Comment: 8 pages, 6 figures
