多目标跟踪的粒子滤波器，与理论分析结果相比，二维声子晶体FDTD方法计算禁带宽度的例子。- Multi-target tracking particle filter, Compared with the results of theoretical analysis, Dimensional phononic crystals FDTD method calculation examples band gap.

很经典的晶体滤波器的理论计算和方法，上世纪60，70年代的经典书籍，望大家笑纳(The theoretical calculation and the method of crystal filter is very classic, 60 of the last century, the 70s classic books, hope you kindly)
