AbstractInterface problems arise when two or more materials meet, they are widely seen in science and engineering. The difficulty of solving interface problems lies in capturing the complex interface geometry and jump conditions effectively while the PDE is not valid across the interface. This talk will present the Petrov-Galerkin Finite Element Method for the numerical solution of elliptic/elasticity interface problems with Bloch-periodic boundary conditions. Its application on the band structure computation of 2D phononic/photonic crystals will also be discussed.
