研究了共振时谐波能量在深槽中的传播效应及其在暂态波场中的表现。在前一篇论文(Glushkov等人，2015[1])开发的半解析模型的基础上进行的大范围参数研究中揭示了这种效应，并使用激光多普勒测振仪对其在预测频率下的出现进行了实验验证。陷阱模理论中的分析提供了对观察到的共振现象的更好的理解。(C)2015爱思唯尔有限公司。保留所有权利。
The effect of resonance time-harmonic wave energy transmission through deep notches and its manifestation in transient wave fields is studied. This effect has been revealed during a wide-range parametric study on the basis of semi-analytical models developed in preceding paper (Glushkov et al., 2015 [1]), Its emergence at the predicted frequencies is experimentally validated using the laser Doppler vibrometry. The analysis within the trapped mode theory provides a better understanding of the resonance phenomena observed. (C) 2015 Elsevier Ltd. All rights reserved.
