Abstract: Metasurfaces have overcome the electromagnetic limitations of traditional natural materials and solved the bottlenecks of difficult processing and implementation of three-dimensional metamaterials, leading devices to continuously develop towards integration, miniaturization, low cost, and tunability. Metasurfaces are widely used in many fields and are increasingly valued in the field of detectors. Through unique material and structural designs, metasurfaces can effectively achieve precise control of various electromagnetic wave characteristics. Through the integration of metasurfaces, microbolometers are more likely to enhance light absorption and improve the device band selection. This article elaborates on the research on metasurfaces and their applications in microbolometers, demonstrating the development trend and broad prospects of metasurfaces in this field.
