Abstract Skyrmions, a stable topological vectorial textures characteristic with skyrmionic number, hold promise for advanced applications in information storage and transmission. While the dynamic motion control of skyrmions has been realized with va

Topological insulators (TIs) with robust boundary states against perturbations and disorders have boosted intense research in classical systems. In general, two-dimensional (2D) TIs are designed on a flat surface with special boundary to manipulate t

Skyrmions with stable vector field configurations have produced various derivatives with various topological textures, such as the Néel type, Bloch type, anti-type, and higher-order Néel type. Here, we theoretically and experimentally demonstrate t

Recently, acoustic skyrmions have been explored by tailoring velocity vectorial near-field distributions based on the interference of multiple spoof surface acoustic waves, providing new dimensions for advanced sound information processing, transport

Here, we experimentally demonstrate a novel strategy for broadband acoustic insulation of an arbitrary shaped region by arranging a localized rainbow trapped metastructure at a deep subwavelength scale. The metastructure constitutes radial gradient g

In this paper, we propose a subwavelength closed surface consisting of radial gradient grooves for achieving localized acoustic rainbow trapping. Similar to conventional rainbow trapping based on a plane structured surface, we demonstrate that rainbo

Manipulating directional electromagnetic scattering plays a crucial role in the realization of exotic optical phenomenon. Here, we show that the spoof plasmonic structure is able to achieve the switching of directional scattering direction on a subwa

Superscattering is usually described as a scattering cross section, induced by degenerate resonances, that exceeds the single-channel limit of a subwavelength scatterer. It has important applications in sensing, bioimaging, and emissions amplificatio
