Tri-Band Optically Transparent Absorption Metasurface for RCS Reduction

An optically transparent tri-band microwave absorption metasurface based on indium tin oxide (ITO) resistive films is proposed. The physical mechanism of the tri-band microwave absorption is revealed by analyzing the surface current distributions. Simulation results demonstrate that the proposed metasurface achieves over 90% absorptivity for vertically incident linearly polarized waves within three frequency bands from 8.85 GHz to 10.3 GHz, 18.63 GHz to 20.88 GHz, and 27.4 GHz to 30.45 GHz. T...

Broadband Multiple Vortex Beam Generation Based on Pancharatnam-Berry Phase Metasurface

In this paper, a metasurface for generating broadband deflection vortex beams based on the Pancharatnam-Berry (PB) phase principle is proposed. The units with different phase responses are arranged according to the calculated vortex phase compensation matrix, thereby the proposed metasurface can convert the incident plane wave into a reflected high-purity third-order vortex wave within a broadband from 14 GHz to 20 GHz, and the relative bandwidth is 35.3%. In addition, by adding beam deflecti...

Mesoporous Copper‐Based Metal‐Organic Framework Flakes as a Promising Platform for Electrosynthesis of Ethylene from Carbon Dioxide

Developing practical electrocatalysts for carbon dioxide electroreduction (CO2RR) requires a synergy of sustainable synthesis and high performance. Here, we report a one-pot green synthesis of a flake-like, mesoporous copper-based metal-organic framework (Cu-MOF) optimized for CO2 conversion. Spectroscopic analysis confirms a coordination environment of Cu2+ centers tetragonally bonded to nitrogen atoms, characteristic of zeolitic imidazolate frameworks (ZIFs). This flake-like architecture an...

High-Voltage Power-Line Conductor Anomaly Detection Using Magnetic Field

This paper introduces a contactless, fully passive approach for locating faults in transmission line conductors. The method relies on the magnetic fields generated by the line current and captures them using low-cost, three-axis magnetic sensor integrated into a custom-designed drone payload. Unlike traditional inspection techniques, the proposed system performs rapid, multi-position magnetic scanning around the conductors within a short time window. By analyzing the spatial variations and te...

The Just Green Transitions Policy Landscape

The chapter analyses the evolution of GT policy at the supranational level, tracing how policy priorities and approaches have changed over time and influenced the shaping of national policies and regional strategies. A special focus is placed on a JGT policy in the Western Balkans, where national policy frameworks are increasingly focused on harmonisation with European and global standards of sustainable development. Cooperation programs that enable the harmonisation of regulatory and institu...
