The classic differential method is applied for modeling the diffraction of light from two-dimensional photonic crystals that consist of dielectric cylindrical objects. Special attention is paid to mutual interpenetration of consecutive layers. Two algorithms for dealing with a stack of repetitive layers are discussed, namely, the eigenvalue technique and the <i>S</i>-matrix algorithm. Their advantages and limitations are analyzed, and times required for their implementation are compared.
