Fig. 3From: High-quality-factor dual-band Fano resonances induced by dual bound states in the continuum using a planar nanohole slabScattering power of the Cartesian ED, MD, TD, EQ and MQ when a Δ = 0, b Δ = − 14 nm, c Δ = − 28 nm and d Δ = − 42 nm. e and f Normalized scattering power of different multipoles with Δ = − 28 nm around Fano#1 and Fano#2, respectively. Other parameters are the same as Fig. 1cBack to article page
