Abstract
In this paper, the rectangular air-slits are etched in a gold thin film is carefully designed and arranged to form a metasurface. We both numerically and experimentally demonstrate the ability to achieve multiple near-field routing possibilities using plane wave excitations. By changing the polarizations of the optical excitation, adaptive routing paths in the near-field are realized and are observed in the far-field via scattering through a circular groove. We anticipate such adaptive routing of SPP a step closer to the widely envisioned optical circuit in the near future.
