| Abstract: | In this study, a new metal–insulator-metal–insulator (MIMI) metamaterial design was made to achieve selective infrared absorption consisting of layers arranged in the form of a metal–insulator (Ag-ITO) O-ring shaped on a planar metal–insulator (Ag-Si) metasurface. The proposed metamaterial design has been studied for the spectral region between infrared wavelengths 800 and 12,000 nm. Spectral features were analyzed using finite difference time domain (FDTD) software. With this design, in the atmospheric windows low emissions have been preserved ε3-5 = 0.15, and ε8-12 = 0.1 in the mid-wave infrared (MWIR) region and, the long-wave infrared (LWIR) region, respectively. Also, a broad-band absorption with a maximum value of 98% in the near-infrared (NIR) and short-wave infrared (SWIR) regions is achieved. The average absorption value is about 0.80, while in the non-conduction infrared (NTIR) region, the maximum absorption value is 99% at 2054 nm. The average absorption value is about 0.50 in NTIR, resulting in two absorption peaks at wavelengths of 2504 nm and 6420 nm, which perfectly match the thermal camouflage and radiative cooling windows. Combining surface plasmon polariton (SPP) and magnetic polariton (MP) mechanisms in the same structure greatly improves photon absorption in the Si layer. Moreover, the proposed structure is polarization insensitive as it has an in-plane symmetrical design. The optical performance of the structure was optimized using numerical simulation techniques. The impedance values of the nanostructure and air were compared. It was shown that they provide excellent compatibility and that the average absorption values are very close to the desired value in the MWIR and LWIR regions. The designed structure offers an adjustable and highly efficient solution to manage thermal emissions in various applications and is an important innovation in the field of defense technology.
