| contents | Meniscus oscillations at interfaces between liquids, solids, and air significantly impact fluid dynamics and control. While idealized models exist, experimental data on capillary-gravity wave scattering involving meniscus effects remain limited. In this study, we systematically measured wave transmission past a surface-piercing barrier, focusing on meniscus and contact-line effects. By varying the barrier's surface properties and the wave frequencies, we explored how meniscus deformation influences wave transmission. The results are compared with simulations and limiting-case theories. We find that the meniscus water column beneath the barrier enhances coupling and increases transmission, while surface bending suppresses it by constraining motion. These competing effects explain the observed frequency and contact angle dependencies. Our findings provide insights into how meniscus dynamics govern surface wave behavior. |
