Highly curved reflective W-shape and J-shape photonic hook induced by light interaction with partially coated microfluidic channels
Lingya Yu, Zengbo Wang, Lizhou Xu +6
Photonic hook (PH) is a new type of artificial self-bending beam focused by a dielectric particle-lens with a curved waist smaller than the wavelength, which has the potential to r…

Generation of S-shaped photonic hooks from microcylinders with engineered surface patches
Chu Xu, Fen Tang, Qingqing Shang +8
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 ha…

Optical super-resonances in dielectric microsphere particles
Zengbo Wang, Boris Lukyanchuk, Baidong Wu +5
Extreme field localization and giant field enhancement are often achieved by using plasmonic nanostructures and metamaterials such as strongly coupled silver nanoparticles.Dielectr…
