Microwave Resistive Metasurface Absorber: Designing and Grazing Angle Stability

Metamaterials and metasurfaces are a class of artificially constructed materials with microarchitectures specifically designed to exhibit properties not present in naturally occurring substances. These structures demonstrated exceptional behavior that allowed for the manipulation of particles and optical and electromagnetic waves in unprecedented ways. These synthetic materials possess electromagnetic properties that are independent of their chemical constituents; instead, these properties depend on the physical arrangement of the constituent atoms. Consequently, the physical design determines the characteristics of the material. Metamaterials offer greater design flexibility and the potential to achieve novel features, making them a prominent topic in various research fields, including thermodynamics, mechanics, and electromagnetics. They exhibit intriguing features such as negative refraction, cloaking effect, and enhanced absorption. Research on electromagnetic absorbers is rapidly growing due to their promising applications in sensors and stealth. Among these applications, stealth and military uses are particularly noteworthy. From a stealth perspective, grazing stability is a crucial factor. This study provides a brief overview of metamaterials, with a focus on resistive‐based metamaterials for microwave applications. It focuses on advancements in broadband design and grazing angle stability while discussing the applications of resistive electromagnetic metamaterial absorbers. Additionally, it offers forecasts for the future of resistive‐based metamaterials.
