Description:
Author(s): Rui-Peng Guo, Li-Ting Wu, Mu Yang, Tian-Jing Guo, Hai-Xu Cui, Xue-Wei Cao, and Jing Chen We introduce a concept of a k-zero mode, an electromagnetic wave with a nonzero group velocity (∂ω/∂k≠0) but a null phase gradient (k=0). Existence conditions of k-zero modes are discussed. We emphasize that the existence of k-zero modes is closely related to the the unique nonzero lateral displacem... [Phys. Rev.
