Abstract
We present the design and the numerical modeling of electrically-tunable plasmonic metasurface absorber based on the Babinet’s principle in the mid-infrared spectrum. The plasmonic metasurface consist of an array of gold nanoantennas on a dielectric layer followed by gold substrate in a metal-insulator-metal (MIM) configuration. A graphene layer placed on top of the array enables electrical tuning of the antenna optical response. Finite-difference time-domain (FDTD) -based simulations were carried out using a commercially implemented FDTD Solutions to obtain the optical response of the metasurface. Based on the Babinet’s principle, we design and numerically modeled the complementary metasurface. We found that, even with the graphene layer, the complementary metasurfaces comply with the Babinet’s principle. These metasurfaces can found application as electrically-tunable sources in the mid-infrared range.
