Dual-layer ultra-thin polarization-insensitive metamaterial for ultra-wideband microwave absorption
This work proposes a dual-layer ultra-thin polarization-insensitive metamaterial for ultra-wideband microwave absorption. The proposed metamaterial absorber (MMA) consists of two resistive frequency selective surfaces (RFSS) constructed in a grounded dielectric substrate. The two RFSSs, although with the same unit cell...
