Broadband Absorber Based on Metamaterials
Based on metamaterials, a new type of absorber is designed. After the optimization of structural parameters, the absorptivity of this absorber can approach 100%, and the absorption bandwidth is over 18.5 GHz when the absorptivity is larger than 90%. The simulation results show that the electromagnetic energy loss comes mainly from the lumped resistance in the electromagnetic metamaterials. With the decrease of the reflection of the incident wave, and the increase of the absorptivity of the absorber, the broadband absorption can be achieved.
