A wave and Rayleigh–Ritz method to compute complex dispersion curves in periodic lossy acoustic black holes
In this work we first propose a wave and Rayleigh–Ritz method (WRRM) to analyze the
vibrations of periodic systems. It is well-known that one of the main difficulties of the …

Evanescent waves in a metabeam attached with lossy acoustic black hole pillars
In this paper, we suggest a metabeam having periodically distributed integrated acoustic
black holes (IABHs). Compared to conventional embedded ABHs, the thickness of the base …
