A very efficient and simple formulation for analyzing 2D photonic crystals with periodic defects is presented. This method is a combination of lattice sums' matrices and a T-matrix of an isolated cylinder. The numerical examples show the convergence is very fast and the computing accuracy is very high. The scattering properties by three kinds of photonic crystals with periodic defects are investigated, and the propagating nature of a coupled-cavity waveguide are discussed. The validity and usefulness of this formulation is confirmed by the numerical experiments.
