“…In previous works, we have found 15,16 the Fano resonance in a metasurface consisting of a mirrorsymmetric array of SRRs appearing due to the interaction of the lattice mode with the plasmonic mode. In our scheme, the broad plasmonic resonance plays the role of a "continuum", and the lattice mode performs the role of a discrete level.…”
This work demonstrates the first experimental observation of multiple Fano resonances in the terahertz range in a system based on an array of mirror-symmetric split-ring resonators deposited on low-loss and low-refractive index polytetrafluoroethylene (PTFE) substrate. For the first time, selective surface activation induced by laser technology has been used to deposit a copper layer on a PTFE substrate with the further application of standard mask lithography for metasurface manufacturing.

“…It is seen that the SRR, in every second column of the array, is rotated by 180 degrees. Such a configuration has allowed the detection of single Fano resonance earlier 15 , 16 . Figure 1 Schematics of the mirrored array of SRRs and enlarged single unit cell.…”

“…In this work, we present the first experimental observation of multiple Fano resonances in the terahertz range in HMW system based on an array of mirror-symmetric split-ring resonators 15 , 16 . We propose a scheme for multiple Fano resonance observation via interaction of plasmonic mode with dielectric waveguide modes appearing in a mirror-symmetric array of SRRs deposited on low-loss and low-refractive index polytetrafluoroethylene (PTFE) substrate.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
