Superior microwave shielding modulation based on rapidly prepared graphene metasurface.

ABSTRACT: Active manipulation of electromagnetic wave jamming is a critical challenge for next-generation adaptive electronics. Electrical conductivity-tunable porous materials have been developed, but have encountered the challenge of constrained modulation range and large thickness. Herein, we report a method for modulating the shielding efficiency of microwaves based on a micrometer-thick graphene metasurface. The continuous modulation between wave transmission and shielding in an ultra-wide range of 9.66%-99.78% is achieved, due to the remarkable anisotropy of wave-induced electron oscillation. By rotating the metasurface, wherein alignment of the periodically arranged graphene strips with the incident electric field enhances electron oscillations and boosts secondary radiation, significantly im
