We propose a highly efficient broadband tunable metamaterial infrared absorption device. The design is modeled using the three-dimensional finite element method for results show that device captures over 90% of light in wavelength range from 6.10 μm to 17.42 μm. utilize VO2’s phase change property adjust device, allowing average level vary between 20.61% and 94.88%. In this study, we analyze electromagnetic field distribution at its peak point find high achieved through both surface plasmon resonance Fabry–Perot cavity resonance. structural parameters are fine-tuned parameter scanning. By comparing our work with previous studies, demonstrate superior performance design. Additionally, investigate polarization angle incident it insensitive these factors. Importantly, simple structure broadens potential uses photodetection, stealth, sensing.
