Enhanced Acoustic Adhesion Enabling Agile and Small Wall‐Climbing Robot Design With Anisotropic Origami Structure

open access: yesAdvanced Science, EarlyView.
This 28 g robot incorporates innovative ring structures and anisotropic origami springs to achieve high speeds and exceptional load capacity. It successfully carries a 100 g payload while ascending walls or ceilings at speeds of up to 8 and 20 cm/s, demonstrating enhanced adhesion and maneuverability over current climbing robots.

Hardware‐Native Gaussian Sampling With Probabilistic Ising Machines for Modern Communication Paradigms

open access: yesAdvanced Science, EarlyView.
Probabilistic Ising machines are introduced as hardware‐native Gaussian samplers for edge communication workloads. Tunable variance and sampling density enable accurate distributions for Falcon‐class post‐quantum signatures and diffusion‐based semantic communication.

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.

Broadband Near‐Field Computational Microwave Imaging Enabled by Nonperiodic Dispersive Unit‐Cell Loading in a Passive Metasurface

open access: yesAdvanced Electronic Materials, EarlyView.
A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish

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.
