A novel thin metamaterial wideband radar absorber formed by two layers of resistive Hilbert curve arrays is reported. HFSS simulations reveal a reduction in the monostatic radar cross-section of more than 10 dB from 8 to 18.8 GHz (81 fractional bandwidth) for Ex and 9.1 to 20.7 GHz (78 fractional bandwidth) for Ey polarisations, respectively. This bandwidth is significantly wider than those reported...
