Resumo
The transmission spectrum of a holographic sensor (silver nanograins embedded in a polymer matrix) is shown to be well described by expressions for the Rayleigh light scattering and absorption by silver nanograins. The optical characteristics of the medium are determined in the Maxwell Garnett approximation. In the presence of a holographic structure, a dip appears in the spectrum. A possibility of obtaining the approximating curves depends on the approximation range. The spectra are well approximated both in the presence and in the absence of an interference structure. For different approximation ranges, the dip parameters coincide despite the values of the background parameter associated with absorption can differ significantly.
