摘要: We propose an ultra-broadband and polarization independent planar absorber comprising multilayered graphene. The bandwidth of the proposed absorber is extended by increasing the number of layers of graphene, and it is polarization independent due to its symmetrical unit structure. The full wave simulation results show that an absorber with three graphene-based layers can efficiently harvest an electromagnetic wave with random polarization from 17.9 GHz to 188.7 GHz (i.e., covering frequency regimes from K to D bands and relative bandwidth of~165%). The physical absorption mechanism of ultra-broadband absorption has been elaborated upon using the destructive interference method and multiple resonances approach in a multilayered medium. The proposed absorber can be used in many applications such as medical treatment, electromagnetic compatibility, and stealth technique.
