A graphene‐metamaterial hybrid structure for the design of reconfigurable low pass filters in terahertz region is proposed. This design manages to manipulate the resonance characteristics of metamaterial and terahertz wave response characteristics of the hybrid structure by controlling the chemical potential of graphene. The shift of the resonant frequency and the modulation of the resonant peak of the metamaterial, which have negative effects on the performance of the proposed filter, were studied and the thickness of the dielectric layer between graphene and metamaterial is found to play an important role. Finally, a reconfigurable pass band with a maximum modulation depth of ~ 32% at 0.1THz is obtained.

石墨烯-材料混合结构，用于可重构低通太赫兹滤波器的设计

提出了用于太赫兹区可重构低通滤波器设计的石墨烯-材料混合结构。此设计通过控制石墨烯的化学势来控制超材料的共振特性和杂化结构的太赫兹波响应特性。研究了超材料的共振频率偏移和共振峰的调制，这对所提出的滤波器的性能有负面影响，研究发现石墨烯和超材料之间的介电层厚度起着重要作用。最终，获得了一个可重配置的通带，在0.1THz时的最大调制深度约为32％。
