a Illustration of the enhanced third harmonic generation scheme by the Super-Fano resonance mechanism. This formation involving electric dipole, magnetic quadrupole, and electric quadrupole modes. b Transmittance spectra associated with the corresponding modes forming single resonances. c The resultant transmittance spectrum originated from coupling of these three modes with strength κ, forming the Fano-like sharp asymmetric resonance profile. d The corresponding TH spectrum of high intensity
