We present a new design for metamaterial (MM) absorber that is resonant with strong absorbance in the microwave frequency range. Our fabricated MM consists of two resonators and a metal wire that couple separately so as to absorb all incident electric and magnetic fields within a single-unit cell layer. Experiments demonstrated that the transmission coefficients (S21) are lower than -10 dB across the entire measurement frequency range, and the reflectance coefficients (S11) are about -20 dB around 10.4 GHz. The absorptivity. which can be obtained through S parameter, is greater than 98% around...
