• Term: from 2010 to 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 164260466

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.
