WebFeb 22, 2024 · Here, we design and build a metagrating to control the reflection direction of waterborne ultrasound waves impinging on a rigid or free surface. The grating and its atoms are designed to cancel the specular reflection and to redirect acoustic power toward a negative-reflection direction, through the first-negative-order Floquet mode. WebReflection coefficient of underwater materials can be calculate by measuring impedance above the sample. some techniques which measure reflection coefficient are based on the sound pressure. This paper introduces a method for measuring reflection coefficient with vector hydrophone which can measure the instantaneous sound pressure and sound …
