The project aims at the theoretical and experimental investigation of the spatial propagation and lateral confinement of surface plasmon polaritons on specifically designed meta-surfaces. By judicious design of the metamaterial, complete control over the spatial propagation of surface plasmon polaritons in the plane of the meta-surface shall be achieved. The propagation of the surface plasmon polaritons is calculated based on three-dimensional numerical models. After successful numerical evaluation of the accomplished meta-surface designs, the meta-surfaces are fabricated by micro- and nano-fabrication methods and the propagation of surface plasmon polaritons is measured by spatially resolved terahertz near-field spectroscopy.

该项目旨在对表面等离子体激元在专门设计的元表面上的空间传播和横向限制进行理论和实验研究。通过对超材料的明智设计，将实现对超表面的平面中的表面等离子体激元的空间传播的完全控制。基于三维数值模型计算了表面等离子体激元的传播。在成功的数值评估完成的元表面设计后，通过微米和纳米制造方法制造的元表面和表面等离子体激元的传播测量的空间分辨太赫兹近场光谱。
