标题： Resonance of an object floating within a surface wavefield

摘要： 我们研究浮置圆柱形物体与重力区域表面波之间的相互作用。 鉴于与浮置物体相关的共振现象的影响，尤其是在实验室尺度下仍缺乏深入研究，我们关注浮置物体的共振频率对波辐射的影响。 我们研究浮置刚性圆柱体对外部机械扰动的响应。 使用光学重建技术测量波场，我们研究浮置物体在几何形状中的自然共振频率及其对入射波的响应。 结果表明，共振频率受圆柱体几何形状和固-液密度比之间的相互作用影响。 入射波实验表明，浮置物体衍射波，产生扩散和逆向扩散的复杂图案，同时辐射出与入射波场发生干涉的次级波。 在共振频率处观察到最小的波生成。 这些发现为阐明较大结构（如海冰浮块）在自然波场中的行为提供了见解。 显示英文摘要

摘要： We examine the interaction between floating cylindrical objects and surface waves in the gravity regime. Given that the impact of resonance phenomena associated with floating bodies, particularly at laboratory scales, remains underexplored, we focus on the influence of the floaters' resonance frequency on wave emission. We study the response of floating rigid cylinders to external mechanical perturbations. Using an optical reconstruction technique to measure wave fields, we study the natural resonance frequency of the floaters in geometry and their response to incoming waves. The results indicate that the resonance frequency is influenced by the interplay between the cylinder geometry and the solid-to-fluid density ratio. Experiments with incoming waves demonstrate that floaters diffract waves, creating complex patterns of diffusion and retro-diffusion while radiating secondary waves that interfere with the incident wavefield. Minimal wave generation is observed at resonance frequencies. These findings provide insights for elucidating the behavior of larger structures, such as sea ice floes, in natural wave fields.
