In this paper, we have proposed and designed a new dual-band metamaterial absorber based on impedance-matched theory. The electromagnetic properties of rectamaterial absorber sample were measured using free space method in microwave frequency from 8 to 18 GHz. The mersured resultes indicated that the transmission coefficients （S21） are lower than -10 dB across the entire measurement frequency range, and the reflectance coefficients （S11） are -16 dB and -12 dB around 9.5 GHz and 16.5 GHz, respectively. The measurement results of the transmis...
