Enhancing light-matter interactions is particularly important in the field of micronano optics, which can be achieved through plasmon-induced transparency. A new type of metasurface consisting of a single layer of graphene is mainly investigated in the study. This structure is mainly composed of a graphene strip and two graphene blocks, generating plasmon-induced transparency at terahertz frequencies via weak coupling between the two bright modes. Furthermore, the time-domain finite-difference method (FDTD) and coupled-mode theory (CMT) are utilized to further explore the physical mechanism of...
