Abstract :
Phononic crystals (PnCs) can be designed to control and confine elastic waves. We present and use the optimization algorithm based on the two-stage genetic algorithm (GA) and the finite element method (FEM) to carry out the band gap optimization of the two-dimensional (2D) solid-solid binary-component PnCs.
