Calculated distribution of electric field intensity near PVA/air interface under the illumination of a plane wave source. (a–d) Intensity distribution near single spheres, the diameters are (a) 0.3 \(\mu \)m, (b) 0.86 \(\mu \)m, (c) 1 \(\mu \)m, (d) 1.7 \(\mu \)m. (e) Intensity distribution near a 5-spheres aggregation, the diameter of the spheres is 0.86 \(\mu \)m. (f) Intensity distribution near the PVA/air interface in a wide scope ranging from \(x=-30\ \mu \)m to \(x=30\ \mu \)m.
