Plane Wave-Perturbative Method for Evaluating the Effective Speed of Sound in 1D Phononic Crystals
A method for calculating the effective sound velocities for a 1D phononic crystal is presented; it is valid when the lattice constant is much smaller than the acoustic wave length; therefore, the periodic medium could be regarded as a homogeneous one. The method is based on the expansion of the disp...
