Fig. 4

Distributions of electromagnetic field and displacement current of Fano resonances of the superlattice of the PNS, the color bar represents the field amplitude, and the red arrows indicate field vector or displacement current vector. Other parameters are the same as Fig. 1c with Δ =  − 28 nm. a and c Distributions of electric field amplitude and displacement current vector of Fano#1 and Fano#2, respectively. b and d Distributions of magnetic field amplitude and magnetic field vector of Fano#1 and Fano#2, respectively
