Broadband acoustic transducer |
摘要 |
An acoustic transducer having impedance matched layers that can be deployed in environments having wide temperature variations. An anisotropic layer provides a low coefficient of thermal expansion orthogonally to the direction of sound wave propagation. The anisotropic layer may be a solid matrix embedded with fibers, such as glass, arranged in a common orientation.
