Figure 6: On the left, TM bands along the Γ-X direction for a 2D structure with a PSi layer of 40% porosity ( 𝜀 = 4 . 8 4 ) are represented. On the right pane, TM transmittance response for the same structure in the same direction is shown. In both graphs, the frequency is given in normalized units ( 𝑎 / 𝜆 ).
