This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys. Lett. 70 3218 There are 3 programs, one for short, one for elastic long and the other one is for acoustic long(This script will attempt to find the band gaps in a phononic crystal by carrying out a Plane Wave Expansion of the various quantities It is for an acoustic wave equation with pressure instead of the displacement as prescribed in App. Phys.
