A central spiral split rectangular-shaped metamaterial absorber surrounded by polarization-insensitive ring resonator for S-band applications

This paper reports a central spiral split-rectangular-shaped metamaterial absorber surrounded by a polarization-insensitive ring resonator for s-band applications. The rated absorption is 99.9% at 3.1 GHz when using a three-layer structure where the top and ground are made of copper and the center d...
