Metamaterials for control of acoustic radiation forces

该项目旨在研究声波如何对物体施加力，以及这些力如何通过被称为声学超材料的人工工程结构来控制。该项目预计将导致对声辐射力的新理解，以及如何以高分辨率有效地操纵它们。预期成果是测量精密机械结构的新能力，避免现有系统的成本、复杂性和副作用。这将有利于许多高技术领域，包括充气空间结构、微机械传感器和致动器以及精密光学部件，以及昆虫飞行和通信研究等生物领域。

This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids the cost, complexity and side-effects of existing systems. This should benefit many high-tech areas, including inflatable space structures, micro-mechanical sensors and actuators and precise optical components, as well as biological areas such as the study of insect flight and communication.
