We present a design for metamaterial absorber which is resonant with strong absorbance in the microwave frequency range. Our fabricated design consists of two resonators and a metal wire that couple separately so as to absorb all incident electric and magnetic fields within a single planar layer which is only 0.9 mm thick. Experiments demonstrate 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 ...
