Abstract

In this research, we suggested a multi-band metamaterial absorber for thin film sensing. This absorber is composed of a three-layer structure and has the following layers: a patterned multi-split layer of electrical ring resonators, a dielectric spacer layer, and a continuous metal ground layer. According to the findings of the calculations, the absorber has the potential to display three notable absorption peaks despite having a limited bandwidth. In addition, since the absorber surface was coated with an analyte layer, there is a clear red shift at the positions of the three absorption peaks, and the highest sensitivities for each of these places are correspondingly 0.119 THz/RIU, 0.248 THz/RIU, and 0.662 THz/RIU. Because of this, the absorber that has been suggested has substantial potential uses in sensing and detecting. For the purpose of providing justification for the selection of design parameters, a parametric analysis was carried out. In addition, the design was assessed in terms of its polarization sensitivity and angular sensitivity. Terahertz imaging and terahertz spectroscopy are two fields that might make use of the suggested structure in a practical setting.
