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.

Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

open access: yesGeophysical Research Letters
Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question.

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

open access: yesAdvanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting

Fast, accurate and accessible calculations of leaf temperature and its physiological consequences with NicheMapR

open access: yesMethods in Ecology and Evolution
Mechanistic predictions of ecological niches are fundamentally based on energy and mass exchange processes that, to be realistic, must be linked to microclimate and incorporate behaviour and physiology.
