| Abstract: | In this paper, a multiband metamaterials absorber based on C-shape resonant structure is demonstrated. Simulation by CST Microwave studio show that the metamaterials absorber can acheieve absorption up to 99.67%, 99.85%, 98.10%, 99.99%, 99.25% at 3.28 GHz, 3.89 GHz , 6.61 GHz,9.76 GHz and 11.43 GHz respectively.Reflection measured by arch method show that measured result and simulation result are consistent.With the surface current distribution and the equivalent circuit diagram and the theory of ideal impedance matching,the physical mechanism of metamaterials absorber is analyzed. The metamaterials absorber has polarization-insensitive characteristic. |
