(color online) Electric field distribution of x–y plane with different thicknesses of the MgF layer: (a) t = 10 nm, (c) t = 40 nm, and (e) t = 80 nm. Magnetic field distribution of x–z plane with different thicknesses of the MgF layer: (b) t = 10 nm, (d) t = 40 nm, and (f) t = 80 nm. The thicknesses of the top and bottom Ag layers are both 20 nm.
