Design and analysis of ultrathin polarization-insensitive metamaterial absorber for stealth technology applications

This paper presents the ultrathin metamaterial absorber used for military applications. The unit cell structure is simulated on CST microwave studio 2014. It is ultrathin in nature and gives the absorption peak at 11.56 GHz with 99.7% absorbance. This structure represents the wide-band absorption. It is polarization-independent at incident angles for TE-modes and TM-modes. It gives above 99% absorption for all incident angles for TE and TM-polarizations. This structure used for stealth technology, amateur radio, airborne radar.
