Realizing topologically protected ghost surface polaritons by lattice transformation optics
Xianghong Kong, Chuanjie Hu, Xingsi Liu +4
While conventional surface waves propagate along the surface and decay perpendicularly from the interface, the ghost surface polaritons show oblique propagation direction with resp…
