Intelligent reflecting surface and reflecting device

Abstract

An intelligent reflecting surface according to an embodiment includes a reflector unit cell including a ground electrode, a first dielectric layer arranged on the ground electrode, a first electrode arranged on the first dielectric layer, a second dielectric layer arranged on the first electrode, and a second electrode arranged on the second dielectric layer and overlapping the first electrode. A dielectric constant of the first dielectric layer is 2.5 or more and 3.5 or less. A thickness of the first dielectric layer is 20 μm or more and 30 μm or less. A dielectric constant of the second dielectric layer is 2.0 or more and to 4.0 or less. A thickness of the second dielectric layer is 10 μm or more and 30 μm or less.
