Modulation of Surface Plasmonic Bending Beam via Nanoslit Interactions

The discussion of resonance mechanisms for artificial structural units has always been a key to producing highly efficient, active and tunable meta-devices in the fields controlling surface plasmon polaritons (SPPs) generate plasmonic bending beams (SPBs). In this study, an array 20 antisymmetric double V-shaped structures was designed SPB. arms were panned control electric field intensity distributions influence polarization states (such as angles, linearly polarized (LP), left-circularly (LCP) right-circularly (RCP) light) incident light on SPB is discussed. These results can be well explained by theory dipole radiation. numerical simulation are good agreement with theoretical analysis. It hoped that these will help guide subsequent work optimizing generators.
