Variation in the absorption for the different metals considered as top (HR) and bottom (HB) layers for (a) Mode M1 and (b) Mode M2 resonator-based absorber structure. It is observed that in the Mode M1 design of the structure, the wide band absorber is observed for the Au material. The multiband with an amplitude of > 50% is observed for the Ag material in Mode M2 of the resonator design.
