Breaking the Surface: Buoyant Metal–Polymer Open–Cell Hybrid Lattice Metamaterials

Advanced Materials, Volume 38, Issue 61, 2 November 2026.
Open‐cell metal–polymer lattice metamaterials that defy sinking. (a) Injection process of the polyurethane (PU) foam into the titanium (Ti‐6Al‐4V) hollow‐strut lattice creating the open‐cell Ti‐6Al‐4V+PU hybrid lattice, (b) flotation test of a hybrid lattice specimen, and (c) a digital representation and experimental validation of a marine buoy ...

Computation‐Less, Bias‐Free, and Ultra‐Broadband Photodetector for On‐Chip Edge Extraction

Advanced Materials, Volume 38, Issue 61, 2 November 2026.
A computation‐less, bias‐free, and ultra‐broadband photodetector directly converts local optical‐intensity gradients into signed photocurrents through a position‐dependent bi‐directional photoresponse. This intrinsic physical sensing mechanism enables single‐pixel edge extraction from the near‐infrared to the long‐wave infrared at room temperature ...

CoSP: Reconfigurable Metamaterial Inverse Design via Contrastive Pretrained Large Language Model

Advanced Science, Volume 13, Issue 61, 3 November 2026.
In this work, CoSP (contrastive multi‐state pretrain), an intelligent inverse design method for reconfigurable metamaterials based on a contrastive pretrained large language model, is proposed. Numerical experiments demonstrate that CoSP can design reconfigurable metamaterial structures for multi‐state, multi‐band optical responses, showing great ...

A Nearly Perfect Implementation of a Broadband Optical Null Media via Space‐Folding

Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.
A space‐folding optical null medium with impedance‐matching layers enables broadband directional wave projection and wavefront engineering. By tailoring the folding ratio and dilution ratio, the structure maintains near‐unity transmittance over 5–9 GHz.

Quantifying the Transmit‐Power Threshold for Reliable Passive Detuning of Inductively Coupled Wireless Resonators in MRI: A Phantom Study

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
Wireless MRI resonators rely on passive detuning to prevent local transmit‐field amplification. We introduce an image‐based method to quantify the transmit‐power threshold for reliable detuning using gradient‐echo images acquired over a range of flip angles.

Liquid‐Induced Healing Enables High‐Performance Microlattice Metamaterials in Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Laser powder bed fusion (LPBF) enables the fabrication of complex superalloy microlattice metamaterials, but internal defects and micro‐segregation severely impair their performance. While conventional hot isostatic pressing (HIP) is widely used for volumetric defect closure, maintaining geometric fidelity remains challenging for fine‐featured

Advances in High‐Temperature Microwave‐Absorbing Materials With Rare Metals: Preparations, Classifications, and Strategies

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT High‐temperature microwave‐absorbing materials (HTMAMs) are vital for the electromagnetic stealth of hypersonic aircraft and aerospace engines. Traditional carbon‐based or magnetic‐based absorbers suffer from oxidation, Curie‐temperature limitations, and impedance mismatch under extreme conditions.
