Abstract

A metasurface reflector includes: a first metal layer and a second metal layer stacked in a first direction; and a dielectric layer provided between the first metal layer and the second metal layer in the first direction. The dielectric layer includes a main surface on which the second metal layer is provided. The metasurface reflector is divided into a plurality of unit regions arranged in a second direction along the main surface and in a third direction along the main surface and intersecting the second direction. The second metal layer includes metal units respectively provided in all or some of the plurality of unit regions. Lengths of metal units, which are arranged in the second direction and set for a same wavelength among the metal units, in the second direction are different from each other.
