Rough metallic surfaces cause severe scattering to surface plasmon polaritons (SPPs), thereby limiting the SPP transmission efficiency. Here, we propose a general scheme to design ultra-compact plasmonic routers that can confine and guide SPPs on arbitrarily shaped rough surface. Our strategy makes...
