From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

open access: yesAdvanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Transparent and Flexible Broadband Microwave Absorber Based on a Nested Open‐Ring Metallic Mesh Architecture

open access: yesAdvanced Electronic Materials, EarlyView.
A flexible transparent microwave absorber is developed using a nested open‐ring metallic‐mesh structure, achieving over 90% absorption from 4.9 to 12.3 GHz with 75.8% visible transmittance. The device also maintains stable broadband absorption under bending, demonstrating its potential for flexible transparent electromagnetic protection.
