The invention discloses a multi-component gas detection device and method based on a metasurface quasi-continuous domain bound state. The advanced nanometer manufacturing technology and the deep learning algorithm are adopted, and high-precision, high-sensitivity and high-selectivity gas detection is achieved. According to the invention, the metasurface array with specific design is utilized, and the quasi-continuous domain bound state in the middle-infrared band is realized by accurately regulating and controlling the geometric parameters and material characteristics of the microstructure, so that excellent optical response is obtained. In combination with a deep learning algorithm, complex spectral information is converted into accurate gas composition and concentration information, and a reliable solution is provided for the fields of environmental monitoring, industrial production, safety monitoring and the like. 本发明公开了一种基于超表面准连续域束缚态的多组分气体检测装置及方法。本发明采用先进纳米制造技术和深度学习算法，实现了高精度、高灵敏度和高选择性的气体检测。本发明利用特定设计的超表面阵列，
