Abstract

This paper presents the design of dual band polarization insensitive metamaterial absorber at 9 GHz and 10 GHz. The unit cell of the metamaterial consists of four circular rings copper with copper lines printed on 0.8 mm thick FR4 substrate with dielectric constant of 4.6 and loss tangent of 0.019. The simulated result shows that the dual band metamaterial absorber achieves 97.00% and 97.77% for normal incident electromagnetic waves at 9 GHz and 10 GHz respectively. The corresponding full width half maximum (FWHM) are 3.59% and 3.31%. The simulation result verified that the absorber well performance at any polarization of incident electromagnetic waves.
