Abstract
An acoustic cloak [1] is a metamaterial device that can bend acoustic waves around their interior and hide any object inside from an incident acoustic field. The current methods of designing acoustic cloaking devices involve traditional methods such as direct computer simulation, topology optimization, stochastic optimization, gradient-based optimization (GBO), and more recently data-driven machine learning models. This project focuses on implementing GBO strategies to optimize an objective function of interest, improving our models developed earlier [2, 3] to reduce the cost of design and improve the efficiency of cloaking devices. Acoustic cloak design is achieved by minimizing the total scattering cross section (TSCS) for a set of cylindrical rigid scatterers.
