Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Time‐Domain Content‐Addressable Memory Based on Single Ambipolar Ferroelectric Memcapacitor for High‐Density and Highly‐Precise Distance Function Computation

open access: yesAdvanced Electronic Materials, EarlyView.
A high‐density and highly‐reliable capacitive time‐domain (TD) content‐addressable memory (CAM) based on a single ambipolar ferroelectric memcapacitor with band‐reject‐filter‐shaped capacitance‐voltage characteristics is proposed. The proposed TD CAM performs linear Hamming distance computation via propagation delay modulation, achieving improved ...

46‐Channel Image Encryption Based on Optically Controlled Metasurfaces

open access: yesAdvanced Electronic Materials, EarlyView.
A metasurface‐based optically‐controlled image encryption device is proposed, enabling 46 encryption channels and dynamic capabilities. The terahertz isotropic phase metasurface switches between encryption channels in response to the structured infrared light incident on its surface.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize
