Abstract

This paper presents a chemical sensor using a metamaterial absorber, which consisted of an Au Bottom layer, a FR4 substrate and a double-split-square-resonator (DSSR).The resonance generated by DSSR, which is extraordinarily sensitive to changes of the effective dielectric constant around the capacitive gap. The proposed sensor shows a great sensitivity and a high value of Q by a creative periodic DSSR structure and the Au Bottom layer. In addition, the relationship between the absorption frequency and chemical concentration is demonstrated by simulation.
