Terahertz time-domain spectroscopy of surface plasmon polaritons on periodic metal arrays

Michael Martl, J. Darmo, Josef Kröll, K. Unterrainer

Abstract

This contribution focuses on surface plasmon polaritons at terahertz frequencies. The coupling to surface plasmon polaritons is provided by periodic metal arrays with different structures and distinct dimensions. For these different geometries the generation and propagation of surface plasmon polaritons are studied. A full wave calculation of the interaction of THz radiation with the metal arrays has revealed good correlation between experiment and theory.
