Abstract
• In this study, we will investigate the theoretical foundations of the hexagonal grating structure and its possible advantages in the field of underwater acoustic wave sensing. Specifically, we will focus on how this structure could improve the accuracy of measurements. To demonstrate the practicability and efficacy of this novel technique, we will also go into detail on the design process, optimization strategies, and numerical simulations. • The problem at hand is the limited sensitivity, directional accuracy, and durability of existing underwater acoustic sensing technologies, which hinder their effectiveness in capturing subtle acoustic signals and environmental conditions in dynamic underwater environments. Conventional sensors, such as hydrophones, often struggle to provide the necessary precision and robustness required for applications ranging from marine research to underwater surveillance and environmental monitoring. • The objective of this study is to address these limitations by modelling and designing a specialized hexagonal grating structure for underwater acoustic wave sensing, with the aim of significantly improving sensitivity, directionality, and durability, thus providing a promising solution to enhance the performance and capabilities of underwater acoustic sensing technology. In this paper, we aimed to solve the complex process of modelling and industrialized a hexagonal grating structure that is specifically designed for applications involving the detection of acoustic waves occurring underwater. Because of the diverse and ever-changing properties of the aquatic environment, underwater sensing provides a unique set of challenges. We have designed and optimized a hexagonal grating structure to address these issues and improve the sensitivity and performance of acoustic wave detection by developing a cutting-edge solution for efficient and precise underwater acoustic wave sensing using a combination of numerical simulations and iterative design improvements. This study emphasizes the critical role that this specific grating design has in pushing the boundaries of technology for underwater acoustic wave detection. It offers critical insights and solutions for a variety of applications, such as marine research, underwater surveillance, and environmental monitoring.
