Unidirectional Invisibility Induced by Complex Anti-Parity–Time Symmetric Periodic Lattices

Unidirectional Invisibility Induced by Complex Anti-Parity–Time Symmetric Periodic Lattices

Complex anti-parity-time symmetric periodic lattices, in a wide frequency band, can act as unidirectional invisible media. The reflection from one end is suppressed while it is enhanced from the other. Furthermore, unidirectional laser points (ULPs) which correspond to the poles of reflection from o...
