A broadband polarization-insensitive metamaterial absorber based on multi-mode resonance

In this paper, a novel metamaterial absorber is proposed. The absorber is based on metamaterial which is a kind of artificial periodic structures. The top layer of the absorber is composed of split ring resonators (SRRs) with a square metal patches (SMPs) in each SRR and its bottom layer is covered with whole metal. The special structure of the top layer… CONTINUE READING
