Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

Acoustic/elastic metasurfaces as a kind of two-dimensional metamaterials are of
subwavelength thickness and show remarkable ability of acoustic/elastic wave …

Perfect wave transmission across dissimilar media is critical in wave devices. However, the
existing impedance matching theory allows perfect wave transmission only in special cases …

Metasurfaces have remarkable power for steering flexural waves, and most of the existing
studies for phase modulation of the metasurface concentrate on changing the geometrical …

Different from the common tunable elastic metasurface (TEM), like piezoelectric active
metasurface, in this paper, we propose a TEM composed of impedance-adjustable subunits …

We propose a reconfigurable elastic metasurface for broadband plate wave control where
the flexural-dominated plate mode is concerned. The structure consists of a plate with nuts …

Most elastic metasurfaces face the limitation of their passive design, which results in efficacy
only in a narrow frequency band and single structural function. Moreover, as an inherent …

To control the propagation of multi-mode guided waves in plate is very significant in
nondestructive testing and structural health monitoring for identifying damage and detecting …

This investigation proposes a novel elastic metasurface tailored to convert a longitudinal
wave into a transverse wave and vice versa at an arbitrary refraction angle with full (100%) …

Inspired by the recent advance of acoustic metasurface in achieving wave manipulation, a
surface impedance matched method rather than Generalized Snell's Law for designing a …
