In this paper, the spectral properties of the triangular lattice of grana are investigated. By the finite difference time domain method, the transmittance spectra of the structure are calculated and the components of the scattering matrix are determined, which makes it possible to determine the effective parameters of the structure. As a result, it was shown that a two-dimensional lattice of grana can be represented as a homogeneous film with a thickness equal to the height of the grana. It is shown that the positions of the resonances before and after the homogenization of the structure coincide, which makes this method attractive for estimated calculations of the structure.
