摘要
提出了一种基于超材料的亚波长微波吸收体。该结构在2.82 GHz、6.93 GHz、9.74 GHz、10.60 GHz和14.13 GHz五个不同频率上谐振，吸光度分别为99.54%、74.93%、99.50%、99.79%和99.66%。所提出的吸收器的单元电池适合于12 mm × 12 mm × 1.6 mm的小体积。该结构对TE和TM极化波在60°入射角范围内具有良好的极化不敏感性能。利用表面电流分布和功率损耗密度图研究了该吸收剂的吸收现象。
A subwavelength microwave absorber with five resonating modes
A metamaterial based subwavelength microwave absorber is presented in this paper. The proposed structure is resonating at five distinctive frequencies of 2.82 GHz, 6.93 GHz, 9.74 GHz, 10.60 GHz, and 14.13 GHz with 99.54 %, 74.93 %, 99.50 %, 99.79 %, and 99.66 % absorptivity, respectively. The unit cell of the proposed absorber fits in a small volume of 12 mm × 12 mm × 1.6 mm. The proposed structure is polarization insensitive and performs well up to an incidence angle of 60° for TE and TM polarized wave. The absorption phenomenon of the proposed absorber is investigated by surface current distribution and power loss density plots.
