Abstract :
We fabricated large-area substrateless metal meshes with micrometric period. The measured mid-infrared (IR) spectra display resonant features with high Q-factor due to the interaction of the radiation with Surface Plasmon (SP) modes on both faces of the film. The devices can be used for SP-based sensors.
