摘要
采用甲基乙烯基硅橡胶柔性基体和镓铟锡液态合金等研制可调谐超材料吸波体。通过对开口谐振环型、双L型X波段超材料吸波体的动态吸波性能仿真,研究了形变下超材料单元结构的电磁参数如调谐频率、吸收峰值等的变化规律。结果表明,利用硅橡胶材料的可伸缩性,可以实现吸收峰的动态调节。与电调谐超材料吸波体相比,这种机械调谐超材料吸波体更有利于实现装备共形设计,应用更广泛。
In this paper, a metamaterial absorber based on methyl vinyl silicone rubber and Galinstan is designed and studied. Through the simulation on the dynamic absorber characteristics of the openings resonance loop and double L-shape tunable metamaterial absorber at X band, it is researched that the change rule of the electromagnetism parameters such as tunable frequency and absorption peak with the metamaterial unit structure shape changing. The resuh showed that the absorption peak can be regulated dynamically through the scalahility of the silicone rubber. Compared with the electric tuning metamaterial absorber, the mechanical tuning metamaterial absorber in this paper should more conducive to the conformal design of the equipment and more useful.
