Acoustic microscopy and impedance analysis have emerged as pivotal tools in the non‐invasive investigation of biological tissues. By utilising high-frequency sound waves, these techniques deliver ...

Deep-subwavelength acoustic absorbers have received great attention due to their scientific and application values. Porous materials and micro-perforated absorbers, as the most conventional solutions, ...

Absorbing low frequency sound is a big job, or at least, a job for big things. Acoustic absorption systems require big resonant cavities with large amounts of heavy damping material and significant ...
