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

Realizing superior mechanical performance and outstanding multifunction features, yet with
lightweight configuration, simultaneously, has been always a fundamental challenge. Here …

The elastic metasurface with phase discontinuities has received much attention for realizing
diverse wave steering applications. To date, the elastic metasurfaces capable of realizing …

In recent years, it has been shown that Berry curvature monopoles and dipoles play
essential roles in the anomalous Hall and the nonlinear Hall effects, respectively. In this …

The study of the nonlinear anomalous Hall effect (NLAHE) in PT-symmetric systems has
focused on intrinsic mechanisms. Here, we show that disorder contributes substantially to …

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 …

Topological insulators (TIs) have been rapidly developed for their defect-immune capability
of wave transport, and promoted the innovation in designing smart devices with robust wave …
