Manipulating electromagnetic radiation of one-way edge states by magnetic plasmonic gradient metasurfaces
文献摘要：
We theoretically and experimentally demonstrate that magnetic plasmonic gradient metasurfaces(GMSs)can convert a spatially propagating wave to a one-way edge state or vice versa with high efficiency.Consisting of an array of ferrite rods with a rotation gradient introduced to the rod dimers in the unit cell,GMSs can covert an incident wave beam to a one-way edge state with efficiency over 77％,and almost fully radiate into free space from the one-way edge state.The phenomenon arises from the unidirectional coupling of the spatial electromag-netic wave with magnetic plasmonic GMSs,which is evidenced from the photonic band diagrams of the edge state.The one-way edge state can radiate to or be excited from air with different angles by either engineering the gra-dient of the GMSs or tuning the bias magnetic field.By designing magnetic plasmonic GMSs with more exquisite configurations,we can expect many more nonreciprocal properties,adding additional freedom in manipulating electromagnetic waves.
