Background With the rapid development of technology, 3D printing technology is becoming an emerging manufacturing technology, and conventional production modes are being changed gradually. The material can be rapidly and accurately manufactured into various objects with complex shapes in a layer-by-layer material stacking mode, and is widely applied to various fields of aerospace, automobile manufacturing, medical treatment, electronics and the like. In these fields, there is an increasing demand for materials having special properties, and multilayer resonant metamaterial wave absorbers are one of them. The multilayer resonant metamaterial wave absorber can efficiently absorb electromagnetic waves in a specific frequency range by virtue of the unique structure and material characteristics, and has important application values in the aspects of electromagnetic protection, radar stealth, communication equipment and the like. For example, in the field of aerospace, the method can be used for reducing the radar reflection sectional area of an aircraft and improving the stealth performance of the aircraft, and in electronic equipment, the method can effectively reduce electromagnetic interference and improve the stability and reliability of the equipment. The multilayer resonant metamaterial wave absorber is a special wave absorbing structure based on metamaterial design. Metamaterials refer to artificial composite structures or composite materials that have unusual physical properties that natural materials do not possess. The multilayer resonance metamaterial wave absorber realizes efficient absorption of broadband electromagnetic waves by utilizing resonance characteristics of different layers on electromagnetic waves with different frequencies through a carefully designed multilayer structure and mutual cooperation among layers. Each layer has specific geometric shape, size and material characteristics, when electromagnetic waves are incident, each layer can generate resonance under corresponding frequency, and the energy of the electromagnetic waves is converted into other forms of energy (such as heat energy), so that the purpose of absorbing waves is achieved. Compared with a single-layer wave absorber, the multi-layer structure can remarkably widen the wave absorbing frequency band and improve the wave absorbing performance.
