摘　　要：为了实现超材料吸收器在宽波段上具有高吸收效率,本文利用金属和介质层堆砌成具有金字塔结构的超材料吸收器。该种超材料吸收器结构具有90°旋转对称的特性,因此其在任意偏振上均能保持高吸收效率。经过模拟计算可得,本文设计的超材料吸收器在波段为0.747~2.665μm时具有90%以上的吸收效率,而且TE和TM偏振具有相同的吸收效率。In order to achieve high absorption efficiency in wide band,this paper used metal and medium layers to stack up a super material absorber with pyramid structure.This kind of super material absorber has 90°rotational symmetry,so it can maintain high absorption efficiency in any polarization.After simulation calculation,the superma terial absorber designed in this paper has more than 90%absorption efficiency between the bands of 0.747~2.665μm,and TE and TM polarization have the same absorption efficiency.
