Cavity design refers to the process of designing the shape, size, and placement of cavities within a material or structure to achieve specific performance objectives. Cavities can be found in a wide range of applications, including electronic devices, acoustic systems, and medical devices. The design of cavities plays a critical role in determining the overall performance and functionality of the system. This research area involves studying the mechanics, materials, and dynamics of cavities to optimize their design for various applications. Techniques such as numerical modeling, simulations, and experimental testing are commonly used in cavity design research to analyze and optimize cavity performance.
