- The Dirichlet-to-Neumann method is adopted to calculate the band gaps of the two-dimensional phononic crystals with different interface conditions. The system is in a square lattice which is composed of the solid cylinders embedded in a softer material. The cross sections of the inclusions are circular. In a unit cell a linear eigenvalue equation is formulated, from which the band gaps can be obtained. A typicla numerical example is taken to analyze and discuss the roles of the interface conditions. The results show that the Dirichlet-to-Neumann method can provide accurate results and the different interface conditions have significant effects on the band gaps.
