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 ...

Advanced Science, EarlyView.A continuous conductivity gradient is formed in a porous MXene/melamine foam via directional evaporation, thereby improving impedance matching and enhancing electromagnetic attenuation. The resulting monolithic composite delivers absorption‐dominant EMI shielding with ultralow reflection, offering a simple route toward lightweight EMI shielding ...

The effect of standing waves on the attenuation constant for a low‐loss rectangular waveguide
Electronics Letters, 2021 When standing waves are present in a rectangular waveguide, the resistive losses in the walls are not uniformly distributed. This affects the measurement of the attenuation constant.

Advanced Electronic Materials, EarlyView.A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts

High-efficiency transition between rectangular waveguide and domino plasmonic waveguide
AIP Advances, 2015 In this work, we propose an optimized transition structure to realize smooth and high efficiency conversion from the guided wave supported by a conventional rectangular waveguide (CRW) to the domino plasmon polaritons (DPPs) supported by a domino ...

Self‐Sensing Artificial‐Muscle‐Empowered Humanlike Perception, Interaction, and Positioning
Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.The proposed self‐sensorized artificial muscle (SSAM) can sense its length change as small as 0.01 mm via a seamlessly integrated multi‐segment induction coil. The SSAM provides accurate length information regardless of its loadings, driving pressure, or muscle design, adequate for robust data‐driven feedback control.
