A numerical algorithm is designed and implemented based on the joint application of the finite-difference time-domain (FDTD) method with absorbing boundary conditions (a combination of the perfectly matched layer (PML) and Mur first-order conditions) and the total-field/scattered-field technique (TF/SF). A complete formulation of the algorithm is given. The results of computing the spectral characteristics of the 2D photonic crystal with defects in the form of waveguides are presented. They demonstrate that it is possible to conduct calculations in a wide range of frequencies.
