The ANNs models of the periodic defected ground structures and a novel combinatorial nonperiodic defected ground structures with the characteristic of double stop band have been developed in this paper. The structure sizes of DGS and the frequencies are defined as the input samples of ANNs, the parameters of transmission coefficient calculated by FDTD method are sampled and defined as the output samples. For the PDGS with biggish structure sizes the transmission coefficients have the tiny dither owing to abnormal disturbance and the training samples have been smoothed by the least square method and five-spot triple smoothing method.

本文采用神经网络对周期性缺陷接地结构和一种新型的具有双阻带特性的组合式非周期性缺陷接地结构进行分析建模，将其结构尺寸和频率作为输入样本，对FDTD法计算出的传输系数参数进行抽样并将抽样结果作为输出样本，然后采用贝叶斯正则化算法对神经网络进行训练。

The computation model had 5 parameters, which could be identified by displacement inverse algorithm. At the same time, the ground deformation limits of highways to determine the engineering treatment scope of goafs were provided. On such a basis, the problem could be solved. Finally, a case of Lei-Yi highway was given. The computed results showed that the present method could successfully solve the ground deformation problems of goafs.
