  • 设计并制作出极化无关双向吸收超材料吸波体.仿真结果表明, 该吸波体对斜入射横电极化和横磁极化电磁波具有较好的吸收效果, 其强损耗主要来自介质基板的介电损耗.实验测试结果表明, 该吸波体在11.1 GHz对垂直入射电磁波实现双向强吸收, 吸收率分别为95.9%和90.8%. 该吸波体厚度较薄, 工作波长约为1/34. 该超材料吸波体具有吸收率高、 厚度薄、 设计简单、 易于加工等优点.

     

    In this paper, we design and fabricat a polarization-independent dual-directional metamaterial absorber. The simulation results indicate that the absorber keeps good absorbing performance in a wide incidence angles for both transverse electric and transverse magnetic polarization, and that the high absorption is due to the dielectric loss of substrates. The experimental results indicate that the absorber achieves dual-directional high absorption at normal incidence, and that the peak absorptions are 95.9% and 90.8%, respectively. The metamaterial absorber is very thin, and its thickness is approximately 1/34 of the working wavelength. The metamaterial absorber has many advantages such as high absorption, small thickness, simple design and easy processing.
