The periodic model—(A,C): The absorption cross section of Au NP deposited on Si substrate as a function of the wavelength of incident electromagnetic wave for varying single cell size (A) and varying nanoparticle radius (B). (B,D): The scattering cross section for Au NP deposited on Si substrate; the corresponding cross sections obtained in the case of the single particle model indicated by dashed lines. (A,B): Results obtained from the model of periodic MNP array with constant MNP radii $a=40$ nm and array period taken from the set $\mathsf{\Lambda }=90,100,110,120,160,200,240$ nm.; (C,D): Results obtained from the model of periodic MNP array with varying MNPs radii $a=20,25,30,35,40,45,50,55,60$ nm and the array period $\mathsf{\Lambda }=3a$. All the cross sections are normalized to the particle surface area.
