提出了一种基于单缝非对称金属光栅表面等离子体的定向辐射，实现单向传输的方法。与最近提出的各种非对称单向衍射光栅相比，证明了获得窄光束的可能性。很强的方向选择性可以在很宽的观测角度范围内出现，而入射角不变。(C)2010年美国光学学会
An approach for obtaining one-way transmission in the beaming regime is suggested that is based on the directional radiation of surface plasmons in nonsymmetric metallic gratings with a single slit. In contrast to the various nonsymmetric one-way diffraction gratings that have recently been proposed, the possibility of obtaining of narrow beams is demonstrated. Strong directional selectivity can appear a wide range of the observation angles, while the angle of incidence is retained. (C) 2010 Optical Society of America
