Abstract: ABSTRACT [0015] The present invention relates to a metamaterial-based acoustic cloaking device that incorporates adaptive wave manipulation capabilities specifically engineered for underwater environments. This device achieves effective stealth by redirecting and absorbing incoming acoustic waves such as those from sonar systems while simultaneously attenuating self-generated noise from the enclosed object or vessel. The system combines carefully designed metamaterial layers with integrated sensing and actuation elements that respond in real time to changing acoustic conditions. Through coordinated control of local material properties and wave pathways, the device maintains broadband performance across relevant underwater frequencies, reduces scattering cross-section, and improves operational discretion. The invention further provides a practical manufacturing approach that assembles resilient, pressure-tolerant components into a conformal shell suitable for marine platforms, thereby offering measurable gains in both passive cloaking and active noise management without relying on the fixed geometries or static material responses of earlier designs.
