Abstract

We demonstrate, both numerically and experimentally, that metal–insulator–metal configurations in which the top metal layer consists of a periodic arrangement of nanobricks, thus supporting gap-surface plasmon resonances, can be designed to function as reflective broadband half-wave plates. Using gold as the metal, the constructed wave plates in the near-infrared regime show scalability, bandwidth of 20% of the design wavelength, and theoretical reflectivity above 85%, while a reflectivity of 50% is experimentally measured.
