In this paper, we have proposed an uncomplicated novel graphene-based rectangular nanotetramer patches structure. The prominent single-band filter, graphene plasmon induced transparency, and dual plasmon induced transparency are obtained. Three optical modes can be achieved by the graphene nanoribbon response at different Fermi levels and lengths. These resonances can be adjusted at different frequencies by breaking the structure symmetry due to different formation mechanisms. The theoretical resonance peak fits well with the simulated data after performing a theoretical analysis of the physical mechanisms. The results help us to design optical devices based on plasmonic metasurfaces.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
