Abstract Lattice metamaterials emerge as advanced architected materials with superior physical properties and significant potential for lightweight applications. Recent developments in additive manufacturing (AM) techniques facilitate the of lattice intricate microarchitectures promote their applications multi‐physical scenarios. Previous reviews on have largely focused a specific/single field, limited discussion properties, interaction mechanisms, multifunctional Accordingly, this article critically design principles, structure‐mechanism‐property relationships, enabled by AM techniques. First, are categorized into homogeneous lattices, inhomogeneous other forms, whose principles processes discussed, including benefits drawbacks different fabricating types lattices. Subsequently, structure–mechanism–property relationships mechanisms range fields, mechanical, acoustic, electromagnetic/optical, thermal disciplines, summarized to reveal critical principles. Moreover, metamaterials, such sound absorbers, insulators, manipulators, sensors, actuators, soft robots, management, invisible cloaks, biomedical implants, enumerated. These provide effective guidelines

Abstract Acoustic metasurfaces (AMs) are engineered structures that control acoustic wave propagation, enabling applications such as sound absorption, beam steering, and holography. Most AMs planar operate in a single direction, limiting the spatial extent of target fields. The simultaneous manipulation waves multiple directions remains largely unexplored, omnidirectional have yet to be realized. This study introduces design fabrication approach for capable generating custom fields anywhere 3D space. Inspired by Goldberg polyhedra, method is developed tiling sphere with phase‐shifting unit cells form metasurfaces. balances high sphericity, which ensures omnidirectionality, resolution, prevents aliasing enables diffraction‐limited A strategy also presented, covering design, optimization, construction an internal source.

Abstract To address the growing demands of modern communication systems, design integrated multifunctional metasurfaces has become a key focus research. Janus metasurface enables directional multiplexing by providing independent phase responses to electromagnetic waves from different incident directions, achieving integration in space. Here, novel class is proposed with optical transparency, capable asymmetric transmissions through precise amplitude‐phase joint modulations. The enable holographic imaging planar state and support advanced functions conformal state, such as multifocal convergence multibeam deflection. In experiments, fabricated samples demonstrate excellent alignment objectives, maintaining transparency at ≈38.5%. It believed that unique transmission control capabilities have great potential diverse valuable applications specific environments.

Impedance metasurfaces enable accurate regulation of acoustic fields. However, they can hardly supply a flexible response as such perfect operation is accompanied by stringent requirements on the design unit cells. Actually, an arbitrary lossless and passive target impedance matrix requires tuning 3 independent real parameters. The set composed reflection phase, transmission amplitude, enables representation matrix, possibly possessing singular elements. In this paper, mechanism phase-amplitude-phase modulation (PAP modulation) developed for generic cells metasurfaces. Adjustable are further available under framework. An with mobile parts designed based idea. assembled metasurface handle different incidences field manipulation at given frequency. Beam steering beam splitting considered demonstration examples verified numerical simulation experiment. PAP enriches extends range application theory.
