Title:
ABSORBER OF THREE-DIMENSIONAL METAMATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/127935
Kind Code:
A1
Abstract:
An absorber of a three-dimensional metamaterial, comprising: a reflective layer (1); a wave absorbing layer (2) disposed above the surface on the top of the reflective layer (1); and multiple metamaterial unit array layers (3) disposed above the wave absorbing layer (2). The multiple metamaterial unit array layers (3) and contact edges of the wave absorbing layer (2) are provided in parallel. Each metamaterial unit array layer (3) is divided into multiple identical metamaterial units. An artificial microstructure (4) is attached on a surface of each metamaterial unit facing the same direction. The absorber of the three-dimensional metamaterial further achieves a good wide-angle absorption effect while achieving a good wide-band absorption effect, and can maintain more than 79.5% of average wave absorption effect within an incident angle range of 60º.
