随着科技的发展以及隐身技术在军事上的重要应用,吸波材料在民用和军用领域受到全世界的关注,而结构型吸波材料以自身的优点成为其中的研究热点。设计了一种两层阻抗性、低电导率的相互正交的Hilbert curve宽带结构型吸波材料,采用有限元算法分析其吸波特性。这种结构易于实现,且能在较宽的频带范围内(3GHz-18GHz)提供良好的吸波性能。 With the development of science and technology and the important application of stealth technology in military affairs, absorbing materials have drawn the world’s attention in civil and military fields. However, structural absorbing materials have become their research focus with their own advantages. A two-layer Hilbert curve broadband structure absorbing material with a two-layer resistivity and a low conductivity is designed and its absorbing characteristics are analyzed by the finite element method. This structure is easy to implement and provides good absorbing properties over a wide frequency band (3GHz-18GHz).
