Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures

Advanced Science, EarlyView.
Based on two novel SRR configurations and two independent SRR integration approaches, four tunable bandpass metamaterial filters were fabricated with an ultra‐thin ceramic substrate. Among them, SM‐2 achieves over 97% electromagnetic wave transmittance, with a minimal 1.15% deviation in its resonant frequency prediction, making them promising ...

Wideband radar cross‐section reduction of patch array antenna with miniaturised hexagonal loop frequency selective surface

Electronics Letters, 2016
Wideband radar cross‐section (RCS) reduction of a microstrip patch array antenna is proposed and investigated. The design is based on replacing the solid metal ground of the antenna with a frequency selective surface (FSS) consisted of miniaturised ...

Reduction of a Radar Cross Section Using Active Antenna Elements

, 2019
The traditional approaches to reducing an object's radar cross section are passive in nature, such as changing the shape of an object or coating the object with a non-reflecting material.

G6PC Downregulation Promotes Renal Calcium Oxalate Stone Formation via Lactate‐Induced SNAIL1 K206 Lactylation and Epithelial‐Mesenchymal Transition

Advanced Science, EarlyView.
In renal calcium oxalate stone formation, G6PC downregulation leads to lactate accumulation. This lactate mediates CBP/p300‐dependent lactylation of SNAIL1 at K206, promoting its nuclear translocation. Nuclear SNAIL1 activates the TGF‐β/SMAD3 pathway, driving epithelial‐mesenchymal transition and fibrosis, which ultimately facilitates crystal ...

Mechanically Adaptive Polyimide Interfaces for Stable High‐Voltage NCM–Sulfide All‐Solid‐State Batteries

Advanced Science, EarlyView.
A mechanically adaptive polyimide interface dynamically stabilizes single‐crystal cathodes in sulfide all‐solid‐state batteries. By integrating robust chemical coordination with viscoelastic compliance, this smart coating suppresses parasitic reactions and accommodates cyclic volume expansion.
