Tunable High‐Performance Metamaterial Filters Based on Novel SRR Architectures

open access: yesAdvanced 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 ...

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China

open access: yesAdvanced Science, EarlyView.
Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...

Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐
