Abstract Structured planar materials known as metasurfaces enable versatile manipulation of electromagnetic waves at subwavelength scales. Especially, metasurfaces can serve as spatial sampling lattices that encode prescribed in-plane momentum profiles, as commonly employed in phase-gradient and Pancharatnam–Berry metasurfaces. However, such momentum-encoded metasurfaces typically lose global periodicity, complicating rigorous analyses.

Abstract Sustainable energies from weather are the most ubiquitous and non-depleted resources. However, existing devices exploiting weather-dependent energies are sensitive to weather conditions and geographical locations, making their universal applicability challenging. Herein, we propose an all-weather sustainable glass surface integrating a triboelectric nanogenerator and radiative cooler, which serves as a sustainable device, harvesting energy from raindrops and saving energy on sunny days.
