▎ 摘  要

Investigation was made of metamaterial configuration having the metasurface comprising pixelated graphene-strontium titanate squared pattern. Apart from the constitutive properties of metasurface, the transmission characteristics of the proposed structure were obtained under different angular deformations (which would happen due to strain) in metasurface as well as the graphene chemical potentials and ambient temperatures. It was found that the configurations yield sharp transmission minima corresponding to various parametric and operating conditions, which undergo red- and/or blue-shifts under varying temperature as well as tuning condition. Apart from this, the metamaterial yields polarization-insensitive transmission characteristic. These features can be exploited in tunable temperature and/or strain sensing devices.
