The interest to study the nanoparticles absorbed on the substrate is caused by the multiple practical applications of such systems [1, 2]. The author suggests a method of examining their properties by calculating the absorption and scattering of the electromagnetic field by such system [3,4,5]. It was shown that the Raman scattering and the light absorption can be increased by orders with the use of metal nanoparticles, in particular the noble metal nanoparticles such as Au or Ag. The conducted calculations and simulations allow for investigation of the photocurrent in a semiconductor via the excitation of surface plasmon polaritons in the substrate and resonance picks' emergence. These observations suggest a variety of approaches for improving the performance in photodetectors, integrated optics, biosensing and photovoltaics.
