Description:
Author(s): Zhen Liao, Guo Qing Luo, Hui Feng Ma, Bai Cao Pan, Ben Geng Cai, Yu Feng Yu, and Tie Jun Cui Controlling the propagation of electromagnetic waves at the subwavelength scale is hampered by diffraction. This study uses a chain of connected subwavelength metamaterial resonators to solve the problem, by elegantly improving the coupling strength of localized surface magnetic modes in the planar system. The metamaterial elements are connected physically, so that conduction current can be used to transfer energy efficiently. Of further interest is that the surface wave can be switched between forward and backward modes. These results are expected to impact the design of integrated photonic devices. [Phys. Rev.
