“…10 The resonances are strongly sensitive to the feature sizes of nanoapertures, including the shape, period, thickness, and composition of the metal thin-lm. 4,11,12 For example, there are a large number of studies that explored the coupling effects of electromagnetic waves to triangular, 13,14 circular, 4,6,11,[15][16][17] rectangular, 18,19 elliptical, 20 grating, [21][22][23][24] S-shaped 25 and other irregular [26][27][28][29][30] congurations. Among them, metamaterials such as silver (Ag), aluminum (Al), and gold (Au) were widely used in the aforementioned investigations and showed great electromagnetic characteristics.…”
