Abstract: ABSTRACT Optical pressure, arising from the interaction between light and matter, is typically confined to the range of pico‐Newtons to nano‐Newtons, which limits its practical application in engineering. Here, we propose a two‐dimensional aluminum periodic rectangular nano‐structure designed to enhance and regulate optical pressure through electromagnetic simulations. The distribution characteristics and underlying mechanisms of optical pressure on the nano‐structure's surface are analyzed. The findings reveal that when the dimensions of the nano‐structure are tuned to resonate with the incident field, the rectangular nano‐structure generates significantly enhanced optical pressure compared to a planar surface. Furthermore, the optical pressure can be precisely modulated by adjusting the geometric parameters of the nano‐structure, such as depth, width, and sidewall inclination angle. Our work provides a theoretical foundation for the design and optimization of advanced optical pressure sensors and demonstrates potential applications in precision laser power measurement, non‐destructive testing, and optical propulsion systems.
