Metasurfaces have been employed to control the electromagnetic and acoustic waves. We suggest that the quantum particles can be manipulated with a de Broglie wave metasurface. The effect was achieved by using the dielectric films milled with subwavelength slits, which behave as the quantum meta-atoms with an effective potential energy. The calculations show that ∼100% transmission of de Broglie waves may appear in certain conditions. Moreover, by tuning the effective potential of the slits, a full 360° coverage of transmission phase is attainable. With a carefully designed annular metasurface, highly efficient and subwavelength focusing of de Broglie waves has been theoretically demonstrated. Our work may render a way to manipulate quantum particles.
