We present here a study of the wave propagation in a two-dimensionally (2D) periodic structure. The scattering of a plane wave by a 2D periodic structure is analyzed as a multilayer boundaryvalue problem. Specific examples are given to show quantitatively the stopband behaviors; in particular, a composite structure with different lattice patterns in cascade is shown to achieve the broad and omnidirection behavior of stop band.
