3次元平板におけるガイド波の散乱解析と実験

抄録

This paper introduces a method to perform the scattering analysis of guided waves in a 3-D plate by using the mode-exciting method. This method has computational advantage that numerical methods such as FEM and BEM can be used uncoupled with other technique which make the analysis simpler than other methods. We first explain about the theory of guided wave in a 3-D plate and show the scattering-analysis method based on the mode-exciting method. Some numerical examples are shown and verified by experiments. The analysis and experiment results show good agreement.
