摘要
研究含超材料的新型蜂窝夹层结构复合材料的宽频吸波性能,分析吸波蜂窝高度和蜂窝介电性能对含超材料新型蜂窝夹层结构吸波复合材料吸波性能的影响规律。结果表明:吸波蜂窝高度增加有利于提升超材料结构单元的吸收效果;超材料吸波结构与吸波蜂窝的匹配效果随着吸波蜂窝介电性能的提升,先提高后降低,当吸波蜂窝介电常数实部介于1.59~1.84、介电常数虚部介于1.31~1.75时,匹配效果最好;引入超材料结构单元后,含超材料新型蜂窝夹层结构复合材料低频1~2GHz频率范围的平均吸波性能显著提升,同时材料重量得到大幅度降低。
The wide-band wave-absorbing properties of novel metamaterial honeycomb sandwich structure composites were studied, and the effects of wave-absorbing honeycomb height and dielectric property on the wave-absorbing properties of novel metamaterial honeycomb sandwich structure composites were analyzed. The results show that the wave-absorbing properties of metamaterial structures are improved while the honeycomb heights is increased. The matching effect of metamaterial structures and wave-absorbing honeycomb is improved firstly, and then decreased with the increase of the dielectric properties of wave-absorbing honeycomb. While ε′ is between 1.59-1.84 and ε″ is between 1.31-1.75, the matching effect is optimal. By the introduction of metamaterial structures, the average wave-absorbing properties at 1-2 GHz of novel metamaterial honeycomb sandwich structure composites are significantly improved, and the weight is greatly reduced.
