a Absorption spectra versus diameter of the top TiN nano-disk with the parameters fixed at p x = 200 nm, and t 1 = t 2 = 50 nm. b Absorption spectra versus thickness of the top TiN nano-disks with p x = 200 nm, d = 120 nm, and t 2 = 50 nm. c Absorption spectra versus thickness of the SiO2 layer with p x = 200 nm, d = 120 nm, and t 1 = 50 nm. d Spectra versus polarization angle of the incident light with parameters set as p x = 200 nm, d = 120 nm, and t 1 = t 2 = 50 nm. The color bar denotes the absorption value
