Each of the sheet layers has a sheet substrate and a plurality of man-made microstructures attached on the sheet substrate. The sheet substrate is divided into a plurality of identical unit bodies. Each of the unit bodies and one of the man-made microstructures that is attached thereon form a cell that has an anisotropic electromagnetic property. Each of the sheet layers has at least two cells whose optical axes are unparallel with each other. According to the depolarizer based on a metamaterial of the present disclosure, at least two cells whose optical axes are unparallel with each other are disposed in each of the metalmaterial sheet layers.
