Abstract
A meta device may include: a substrate; a mirror disposed on the substrate; a refractive index modulation layer disposed on the mirror; a nanoantenna facing the mirror with the refractive index modulation layer, the refractive index modulation layer being disposed between the nanoantenna and the mirror; and an insulating layer disposed between the nanoantenna and the refractive index modulation layer and having a non-uniform thickness. Since the thickness of the insulating layer is not uniform, a withstanding voltage characteristic of the meta device is improved.
