Evanescent waves in a metabeam attached with lossy acoustic black hole pillars
TL;DR: In this paper , a wave and Rayleigh-Ritz method (WRRM) is proposed, based on the nullspace method (NSM) that assumes the response is constituted by the linear combination of the null space basis of the constraint matrix.

Tunable reflection and broadband absorption of flexural waves by adaptive elastic metasurface with piezoelectric shunting circuits
TL;DR: In this article , the authors proposed an adaptive elastic metasurface composed of sandwiched plates with mass blocks at their free ends to realize tunable reflection and high-efficiency absorption of flexural waves in broadband.
Journal ArticleDOI
Metasurface-guided flexural waves and their manipulations
TL;DR: In this article , a metasurface-guided flexural wave propagating along and decaying exponentially with the increasing of the distance from the surfaces is considered, and a theoretical framework is established to solve the dispersion relations of these waves by coupling high-order diffraction and waveguide modes.

Surfaces with holes in them: new plasmonic metamaterials
TL;DR: In this article, the existence of surface electromagnetic modes in corrugated surfaces of perfect conductors was explored and it was shown that these structures support surface bound states and that the dispersions of these modes have strong similarities with the dispersion of surface plasmon polariton bands of real metals.
