Achieving strength and toughness limits of anisotropic microstructured alumina ceramics through interface engineering
Nacre-like all-ceramic metamaterials can be programmed by two interface descriptors: the stiffness ratio and the toughness/strength ratio between matrix and platelet to control their toughness.
Layered hybrid lattice architectures for broadband electromagnetic absorption and improved structural stiffness
A hybrid layered lattice design achieves integrated electromagnetic absorption and mechanical stiffness by tuning geometric layer arrangement, enabling multifunctional and lightweight metamaterial absorber applications.
High-dimensional multiplexed metamaterial for cross-media all-sound communication
A high-dimensional multiplexed metamaterial is proposed for modulating all dimensions of sound waves traversing water–air media, enabling high-speed, real-time cross-water–air communications with sound as the sole information carrier.

A novel data-driven electrode structure design and additive manufacturing ensure superior material utilization with minimal ohmic losses and substantially enhance volumetric energy and power densities compared to conventional configurations.
Non-integer-dimensional architected materials enabling synergistic acoustic, mechanical, and fluid coupling
A non-integer dimensional design paradigm enables intrinsic multifunctionality by embedding acoustic, mechanical, and fluid coupling directly into geometry, offering a scalable and fabrication-friendly route for architected metamaterials.
Metamaterials with in situ tunable bending properties
We report a method for designing meta-beams/plates that offer global tunable bending stiffness. This principle enables tunable static bending deformation and vibrational modal shapes and frequencies for beam and plate structures.

Physics-informed neural networks program full energy landscapes of origami metamaterials directly from governing equations, enabling data-free inverse design and controlled sequential deployment.
About this collection
Metamaterials are synthetic composites that exhibit properties not usually found in natural materials. The artificial design of these materials enables properties to be fine-tuned to advance research developments in various fields. They have a diverse range of uses related to, electromagnetics, acoustics, mechanics and thermal materials. This themed collection in Materials Horizons, guest edited by Prof. Grace X. Gu (University of California, Berkeley, USA), Dr. Mohammad J. Mirzaali (TU Delft, The Netherlands), Prof. Amir Zadpoor (TU Delft, The Netherlands) and Dr Wei Zhai (National University of Singapore, Singapore), looks to explore the recent developments in this growing field of research.
We invite researchers working in this exciting field to contribute some of their latest quality work to the collection and we hope the collection will provide a platform to collect some of the latest impactful developments, as well as a platform to inspire new research.
