PWE（平面波展开法）计算二维固-固圆柱形声子晶体的XY模式。-PWE (plane wave expansion method) to calculate the two-dimensional solid- XY mode phonon solid cylindrical crystals.

主要介绍了圆柱形声子晶体在正方格,三角格下的XY,Z模式。共有四个不同的m文件。可供大家参考。-Introduces the cylindrical phononic crystals in the positive square, triangular lattice of XY, Z mode. There are four different m-file. For your reference.
