In this paper, we have proposed and designed a new dual-band metamaterial absorber based on impedance-matched theory. The electromagnetic properties of metamaterial absorber sample were measured using free space method in microwave frequency from 8 to 18 GHz. The mersured resultes indicated that the transmission coefficients (S_(21)) are lower than -10 dB across the entire measurement frequency range, and the reflectance coefficients (S_(11)) are -16 dB and--12 dB around 9. 5 GHz and 16. 5 GHz, respectively. The measurement results of the transmission coefficients and the reflectance coefficients of two frequency pionts are good agreement with simulation results, which indicated that our designed structure have dual-band absorptivity strongly.
