A Hybrid Impedance Matching Network for Underwater Acoustic Transducers

IEEE transactions on power electronics, 2023
The underwater acoustic transducer (UAT) is an electro-acoustic conversion device, which is a nonlinear reactive load. An impedance matching network is usually added between the power amplifier and the UAT.

Broadband low-frequency sound absorbing metastructures based on impedance matching coiled-up cavity

Applied Physics Letters, 2021
We report a kind of sound absorbing metastructure based on micro-perforated panel (MPP) and impedance matching coiled-up cavity (IMCC), which can broaden the low-frequency working bandwidth tremendously using single unit (e.g., 3.13 times compared to ...
