Nanophotonic Devices In article number 1700073 , Li Yu, Jiasen Zhang, and co‐workers create a directional optical travelling wave antenna based on a V‐shaped Ag nanowire, which is fed by surface plasmon modes propagating along the Ag nanowire waveguide. The surface plasmons radiate out at the corner as highly‐directional radiation. The radiation direction can be tuned by changing the surface plasmon modes. Thus, the antenna should have great potential applications in nano‐optics.
