Abstract
Balancing the thickness and bandwidth of electromagnetic wave–absorbing materials has been a challenging task. In this study, a thin and broadband metamaterial absorber consisting of a frequency selective surface (FSS) layer compounded with a magnetic dielectric layer was proposed. The changes in the wave absorbing properties of the absorbers with different numbers of openings in the open circular structure and combinations of open circular rings were analyzed. After obtaining the optimum combination of patterns, the effect of parameter variations on the microwave absorption properties of metamaterial wave absorbers was investigated. The test results show that the optimized metamaterial absorber has a thickness of 1.7 mm, a simulated absorption bandwidth of up to 10.0 GHz, and a microwave reflection loss of less than − 10 dB in the frequency band of 8.0–18.0 GHz. The absorber was prepared and its reflection loss was measured. It is found that these test results have the same trend as the simulation results, which verifies the feasibility of the metamaterial absorber structure design; the proposed two-layer magnetic dielectric composite FSS structure improves the overall impedance matching, avoids the electromagnetic wave being reflected in the surface, and makes the electromagnetic wave enter the interior more; when the resonant absorption peak generated by the introduction of FSS is close to the absorption peak generated by the magnetic dielectric layer, continuous absorption will be achieved, which is the reason for the wide absorption band of the metamaterial absorber. This novel structure takes into account the characteristics of thin layer, broadband absorption, and polarization insensitivity, which has a potential application prospect in stealth technology.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
