Abstract

We propose an innovative structural design based on a metamaterial absorber in the terahertz band. And verified the absorption curve of the new structure by using FDTD software simulation. The absorption curves of the light source at different incident angles and polarizations were simulated.The simulation results show that the multi-layer covering structure effectively increases the absorption bandwidth of the metamaterial absorber in the terahertz band. And the absorption curve is higher and flatter.
