作者介绍了金属-绝缘体-金属（MIM）结构中表面等离子激元（SPPs）的频率选择分束器。在分离器中，一部分spp沿着初始方向直线传播，另一部分spp分裂成直角连接的臂。通过改变MIM中介电层的宽度和介电常数，以及改变所附臂的宽度，可以控制分裂比。(C) 2011 Elsevier B.V.版权所有
The authors introduce frequency selective beam splitters for surface plasmon polaritons (SPPs) in a metal-insulator-metal (MIM) structure. In the splitters, a part of SPPs keeps propagating straight along the initial direction, while the other part is split into the arm attached at right angle. The splitting ratio can be controlled by varying the width and the electric permittivity of the dielectric layer in the MIM, and by varying the width of the attached arm. (C) 2011 Elsevier B.V.
