摘要：

本文对层状周期结构的能量传输谱预测方法进行了研究．在考虑几何参数、物理参数单独变化以及同时变化3种情况下，通过构建深层反向传播(BP)神经网络，实现层状周期结构能量传输谱的精准预测．与径向基函数(RBF)神经网络进行对比实验，实验结果验证了所提方法的有效性．

Abstract:

In this paper, the prediction of the energy transmission spectrum for layered periodic structures is studied. By considering three cases of geometric parameters and physical parameters changing individually or simultaneously, a deep back propagation (BP) neural network is constructed to realize accurate prediction of the energy transmission spectrum of layered periodic structure. A comparison of the predicted results with those obtained by the radial basis function (RBF) neural network verifies the effectiveness of the proposed method.

Key words: layered periodic structure, deep back propagation (BP) neural network, radial basis function (RBF) neural network, energy transmission spectrum, attenuation domain
