Tóm tắt

The authors investigated sandwich structure of the conventional absorber metamaterials to expand the study on dual-band absorption in the previous work (2013 Appl. Phys. Lett. 102 081122). The advantages of the artificial structuring of plasmonic resonators or 'meta-atoms' were exploited to gradually enhance/degrade the absorption peaks by polarization angle of electromagnetic wave. By reshaping the rings at the font of slab, dual- or single-peak absorption is controlled. The absorber is demonstrated in the GHz region.
