Research on sound transmission characteristics of backing material for ultrasound transducers
Based on acoustical designing demand of backing material for ultrasound transducer, the multiple scattering (MS) theory has been studied for different layered medium. The acoustical characteristics of the periodic structure in ultrasonic frequency band have been given as well. In order
to increase acoustic impedance to match the active materials and improve the absorption performance at the same time, it is a good way to fill tungsten powder in epoxy resin and other viscoelastic materials. The test results show that these composites behave good acoustical and mechanical
performance. The new absorbing backing materials make ultrasound transducer have good bandwidth and high sensitivity.
