研究成果
Fractal geometries offer significant benefits in antenna and metamaterial design, including miniaturization, multi-band operation, and improved performance. The integration of fractal shapes with metamaterials enhances electromagnetic properties, leading to compact and efficient devices for modern telecommunications. Future work could focus on optimizing fractal iterations and exploring new fractal-based structures.
研究不足
The paper does not explicitly state limitations, but it implies that fractal structures are abstract and cannot be physically implemented infinitely; pre-fractals or truncated fractals are used, which may not fully capture ideal fractal properties. Additionally, the complexity increases with iterations, and there may be challenges in fabrication and loss management.
