“…These polarizationsensitive nanostructure arrays include aperture array [34], F-shaped nanoslits [35], D-shaped nano-antennas [36,37], multi-lined distribution nanoslits array [29,38], crossshaped nanoantennas [30], V-shaped nanoslits array [39], ring-shaped hologram consisting of slit-pair array [40], C-shaped apertures array [41,42], and multiple rings of nanoslits with special orientations [32]. These studies demonstrate that, by properly designing the spatial orientation of a nanostructure array, the phase of SPPs waves was controlled to reconstruct arbitrary new SPBs wavefront profiles [43].…”

Surface plasmonic bending beams (SPBs), which preserve their spatial shapes while propagating along the desired curved trajectories in a metal-dielectric interface, offer important applications in the fields of fiber sensors, optical trapping, and micro-nano fabrication. In this work, the straight-lined, single-curved and double mirror-symmetric curved distributions of M-shaped nanoslit arrays are designed on a metal film to generate SPBs. These SPBs include unidirectional coupling of SPPs, single arbitrary bending beams, and double arbitrary bending beams. The electric-field intensity and the propagation directions of these SPBs are controlled by the polarization angle of input light waves. Especially, the reverse propagation of unidirectional coupling of arbitrary SPBs is generated by the polarization angles 45° and 135°. These findings provide guidance in the design and optimization of plasmonic bending beam generators.

“…Controlling plasmonic complex fields by polarization-sensitive nanostructure arrays are important for enriching the components of nanophotonic devices to analyze the polarization [29,30]. Various polarization-sensitive nanostructure arrays, such as aperture arrays [29], Fshaped nanoslits [30], Δ-shaped nanoantennas [31], and double-lined distribution nanoslits arrays [32,33], were designed to manipulate propagation directional of SPP waves. Multilined distributed nanoslits arrays were designed to achieve focused SPPs [32][33][34].…”

Plasmonic bending beams, which preserve their spatial shapes while propagating along curved trajectories in metal-dielectric interface, offer important applications in the fields of fiber sensor, optical trapping, and micro-nano manipulation. In this work, circular hole array, as a local point-like sources of surface plasmon polaritons, is designed on the metal film to generate multiple plasmonic bending beams. The electric field intensity of multiple plasmonic bending beams is controlled by polarization angle of input light. In addition, the electric filed intensity of multiple plasmonic bending beams relies on circle hole radius. These findings provide guidance in the design and optimization of plasmonic bending beam generators.

“…gratings [16][17][18], circular coupler based on intersecting slit arrays [19,20] or F-shaped slit arrays [21], were proposed to achieve near-field focused beams The excitation of the near-field focused beams, which are plasmonic hot spots on the surface of a metal film, can be applied in the field of sensing, manipulation and optical tweezers [22]. Studies were conducted to achieve the near-field or low-energy far-field focused beams.…”

In this study, two slits were designed symmetrically on a metal film to excite surface plasmon polaritons (SPPs), and two groups of parallel dielectric rectangles were designed over a metal film to convert the SPPs into double mirror-symmetric spatial bending beams. The high-energy far-field focused beams were achieved by interfering double mirror-symmetric spatial bending beams using the finite-element method The focusing properties of the proposed structure are enhanced compared with the conventional metal grating structures. Furthermore, the effects of the structural parameters on the focusing properties were investigated Results show that the focusing properties of the proposed structure rely on the structural parameters of dielectric rectangles and on the distance between the dielectric rectangles and the metal film. The position of the focusing spot relies on the distance between two slits. These findings can be applied in the fields of biology imaging, nanolithography, optical data storage and photo-biomedical detection.
