Reconfigurable Spoof Plasmonic Skyrmion Electronics for Deformation‐Invariant Multimode Sensing

open access: yesAdvanced Science, Volume 13, Issue 34, 19 June 2026.
A flexible multimode sensor based on capacitively loaded spoof plasmonic skyrmions enables deformation‐invariant dielectric sensing with ultra‐compact size and high Q‐factor. Near‐equidistant resonances remain stable under shape change and bending, while capacitor loading improves bending robustness and multimode sensitivity, highlighting strong ...

High‐Sublimation‐Temperature Additives for Efficient Perovskite Solar Cells via Single‐Source Evaporation

open access: yesAdvanced Energy Materials, Volume 16, Issue 23, 17 June 2026.
The introduction of high‐sublimation‐temperature additives during the mechanosynthesis of FAPbI3 powders enables the single‐source evaporation of phase‐pure, additive‐free FAPbI3 thin films of high optoelectronic quality. The additive‐engineered deposition process yields photovoltaic devices with stabilized efficiencies exceeding 18% for an active ...

Unraveling the 13C Hyperfine Structure of the 5‐Deazaflavin Radical in Solution Using Photo‐CIDNP Spectroscopy

open access: yesChemPhotoChem, Volume 10, Issue 6, June 2026.
The 13C hyperfine structure of the 5‐deazaflavin radical is elucidated by photo‐chemically induced dynamic nuclear polarization spectroscopy and compared to the flavin radical. Despite structural similarity to flavins, 5‐deazaflavins were long thought to act only as two‐electron transfer agents.

A Joint Channel Modeling, Parameter Estimation and Geometry‐Based Indoor Localization for 5G Systems

open access: yesTransactions on Emerging Telecommunications Technologies, Volume 37, Issue 6, June 2026.
We propose an end‐to‐end method to accurately localize mobile stations in indoor scenarios, such as those found in Industry 4.0. To this end, we jointly perform wireless channel modeling considering mmWave and MIMO technologies, parameter estimation in 3D, and simple and fine‐grained geometry‐based localization.

Ultra wideband antenna

IEEE Communications Magazine, 2004
Ultra wideband antennas are specifically designed to transmit and/or receive very short time durations of electromagnetic energy. It is well known that UWB antenna design remains the major factor in the progress of UWB technology. This article describes a study of conventional antennas and why they are not suitable for a UWB system.
