Low frequency tuning of space-folded acoustic metamaterial amplifiers through effective density distribution method.

Space-folded acoustic metamaterials (SFAMs) have exceptional low frequency sound control capability in deep sub-wavelength scale, showing significant potential for weak acoustic signal detection. However, lowering the working frequencies of SFAMs may increase the device size, limiting their applications and raising production costs. To address these issues, this study proposes compact SFAM acoustic amplifiers operating in low frequencies, where their working frequencies are flexibly controlled by engineering effective density without increasing device size.

Sparse Bayesian learning based on spatio-temporal structure-aware for matched field processing.

In the application of the matched field processing (MFP) algorithm for underwater acoustic source localization, the measurements at each time step are conventionally processed independently. This study incorporates the prior information about the continuous spatial changes of the source over time under realistic conditions, a factor anticipated to improve localization performance. In this paper, a sparse Bayesian learning (SBL) algorithm based on the spatio-temporal structure-aware is described.
