【摘要】：为了设计宽角度高吸收的电磁波吸收器件,基于石墨烯超材料,设计了级联的层状结构。利用超材料的特殊属性推导了传输矩阵公式,并利用它研究了所设计结构的传输特性。研究结果表明,在保持高吸收率的条件下,通过调节结构参数,可以实现宽角度吸收带宽。吸收带宽与级联层数有关,但层数达到某个特定的值时吸收带宽趋于饱和。
[Abstract]:In order to design electromagnetic wave absorbing devices with wide angle and high absorption, a cascade layered structure was designed based on graphene supermaterial. The transfer matrix formula is derived by using the special properties of metamaterials and the transmission characteristics of the designed structures are studied. The results show that the wide angle absorption bandwidth can be achieved by adjusting the structural parameters under the condition of keeping high absorptivity. The absorption bandwidth is related to the number of cascaded layers, but the absorption bandwidth tends to saturation when the number of layers reaches a certain value.
