Study on Wide-Angle High-Absorption Based on Graphene Metamaterials
In order to design a wide-angle high-absorption electromagnetic wave absorption device, a cascaded stratified structure based on graphene metamaterials is designed. By means of the special attributes of metamaterials, the transfer matrix formula is derived, which is used to study the transmission characteristics of the designed structure. The research results show that, under the condition that a high-absorption rate is kept, a wide-angle absorption bandwidth can be achieved by adjusting the structural parameters. The absorption bandwidth is related to the number of cascaded layers, however the absorption bandwidth tends to saturate when the number of layers reaches a certain value.
