Metamaterials and Photonic Crystals
Acoustic metamaterials are engineered materials designed to manipulate sound waves in unique ways, often achieving effects that are not possible with conventional materials. They can control sound propagation, absorb sound, or even create sound cloaking, making them valuable in various applications, including sensors and detectors. By structuring these materials at the microscale, they can be tailored to achieve specific acoustic properties, leading to innovative solutions in noise control and imaging technologies.
