摘要：
In this letter, we design a terahertz (THz) multi-band absorber comprised of four square open/closed loops and a ring wall resonant metamaterial with a high absorption rate for TE and TM polarization. Based on resonant response of metamaterial, five different sizes of the metal rings could tune five absorption peaks to produce five-band absorbing performance in the frequency ranging from 0.1 to 1 THz. By comparing the absorber consisting of independent ring with multiple rings, the multi-band absorption could be demonstrated by increasing the number of metal rings. The simulation results are indicated that the multi-band absorbing of the THz absorber is independent of incident angle within a wide range. The design method of the absorber presented can not only provide a theoretical tool to perform diversity absorbing with multiple band and multi-absorption azimuth in terahertz communications, but also has potential for applications in THz imagers, detectors, sensors, and emitters.
