  • Patent number: 11971643
    Abstract: A reflective dynamic metasurface of an embodiment comprises a structure enabling phase modulation in each of pixels constituting at least a one-dimensional array. The metasurface includes: a laminated structure body having a transparent conductive layer and a dielectric layer; a first metal film on one surface of the laminated structure body; a second metal film on the other surface of the laminated structure body; and a drive circuit controlling voltage applied between the first and second metal films. The first and second metal films are arranged to sandwich the pixels. The first metal film is arranged to expose a pair of window regions in one pixel, and the second metal film includes partial metal films defining the shape of each pixel and separated from each other. The drive circuit individually controls the potential of each partial metal film, thereby modulating the phase of the input light for each pixel.
