本報告主要目的是探討斜向入射波浪通過水中浪板時，不同波浪入射角度、浪板長度、設置水深、浪板振幅及波形個數對反射率及透過率的影響。採用的方法為複合邊界元素法(CBEM)，經數值計算後的結果顯示：隨著浪板板長增加，反射率和透過率曲線會愈呈多重震盪型變化。隨著浪板設置水深愈淺，反射率最大尖峰值及透過率最小尖峰值會愈偏往 kh 較小方向。 The main purpose of this paper is to analyze the scattering problems of obliquely incident water waves by submerged wavy plate. Numerical results are presented to illustrate the effects of various wave incident angles, plate length, submerged depth of the plate, number of wavy shape, and the amplitude of wavy plate on the reflection and transmission coefficient. By utilizing the composite boundary element method (CBEM), numerical results show that the two curves of the reflection and transmission coefficient incline to more oscillatory variation as the plate length increases. As the submerged depth of the plate decreases, the maximum peak of reflection coefficient and the minimum peak of transmission coefficient tend to smaller kh.
