Abstract: We propose a method for the calculation of transmission and reflection spectra of close-packed monolayers formed from metal nanoparticles. The model takes into account the correlation effects and electrodynamic coupling in close-packed monolayers treated in the framework of multiple scattering of waves theory as well as the size dependence of the metal nanoparticle optical functions. The transmission and reflection spectra for monolayers consisting of Ag nanospheres are calculated for various particle concentrations and sizes. The matrix influence on the spectral position of surface plasmon resonances for nanoparticle monolayers is considered. The concentration red shift of the plasmon attenuation resonances is shown and the reasons for its appearance are discussed.
