Article Title: Fano Resonances in Metal Gratings with Sub-Wavelength Slits on High Refractive Index Silicon
doi: 10.3390/ma16216982
Figure Lengend Snippet: The mechanism of Fano resonance with a W-shape in transmission curve T(dB) is calculated using the (RCWA) method with a number of harmonics of (N = 150). This calculation is performed for a metallic slit grating sub-wavelength structure with the following parameters: period a = 3 μ m , thickness d ′ = n Si · d = 10.32 μ m , air gap w = a 10 , width of Si Slit g = a 5 , and a refractive index n I I I = n S i = 3.44 .
Article Snippet: Additionally, the RCWA method, implemented in MATLAB by [ ], is employed to model different orders of transmitted and reflected waves by a one-dimensional binary grating in either TE or TM polarization.
