WebApr 1, 2024 · Metal surfaces with intrinsic chirality play an irreplaceable role in many significant enantioselective chemical processes such as enantioselective catalysis, sensing, and separation. Nonetheless, current methods for the precise preparation of such chiral surfaces suffer with issues of unscalable production and low surface areas. Herein, we … WebHowever, current spin-selective metasurface designs have yet to mature into a practical method due to the limitations of single operating band or inefficient phase modulation. Herein, a novel chiral meta-atom is proposed, exhibiting spin-selective absorption/reflection functions for dual-orthogonal CP incident waves at three different operating ...
