Sensing with toroidal metamaterial
, 2017 Localized electromagnetic excitation in the form of toroidal dipoles has recently been observed in metamaterial systems. The origin of the toroidal dipole lies in the currents flowing on the surface of a torus.

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials
Advanced Materials, EarlyView.Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Fabricating Mass‐Producible High‐Performance Metaholograms Using Sol‐Gel‐Processed TiO2
Advanced Materials Interfaces, EarlyView.Mass production of metaholograms on 6‐in. glass is achieved through nanoimprint lithography. TiO₂ sol‐gel is used as an imprint resist, exhibiting a high refractive index in the visible region. Through heat treatment at 600 °C, TiO₂ gel crystallizes into the anatase phase, allowing the fabrication of high‐resolution images with high optical efficiency.
