Abstract
Microwave absorption presents a challenge for the design of metamaterials, which is critical for the stealth and electromagnetic compatibility. To address this, a novel design strategy for patterns is proposed to enhance the wave absorption, which is tortuosity and connectivity. Utilizing the carbon ink composite and genetic algorithm, multi-layer coding metamaterials (MCMs) are designed to satisfy diverse engineering specifications, with reflectivity tests confirming their efficacy. Temperature alternation experiments simulate frequent environmental changes, and the absorptivity of MCMs is compared to evaluate their resilience. This approach ensures the designed MCMs maintain performance and stability under variable thermal conditions, offering a robust solution for advanced applications.
期刊介绍：
Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development.
The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
