Cross-wavelength Metasurface Based on Carbon Nanotubes

Multifunctional metasurfaces have garnered significant interest from both academia and industry in the past decade. However, achieving cross-wavelength functionalities remains a challenge due to the strong dispersion of passive materials. In this study, we propose a novel concept of cross-wavelength metasurface that integrates various functionalities with multispectral channels. As proof of concept, we demonstrate optical transparency, Thz diffusion and microwave selectivity simultaneously in a carbon nanotube based metasurface through a laser micromachining technique.
