Electromagnetic Energy Harvesting Using a Glass Window
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2020 In this work, a new constructive and conceptual model for rectenna, using glass as dielectric substrate, was proposed. This research aims to produce a window for building facades that can harvest the electromagnetic energy available in the environment ...

Further investigation on solant–rectenna-based flexible Hilbert-shaped metamaterials
IET Nanodielectrics, 2020 This study discusses the design of a low-profile metamaterial-based antenna consisting of a 3 × 5 array of Hilbert shaped unit cells organised as a rectangular patch. The antenna is backed by with a partial ground plane loaded with square electromagnetic

The Ionosphere as an Operational Constraint on Space‐Based Solar Power
Space Weather, Volume 24, Issue 9, September 2026.Abstract This commentary argues that there is an urgent need to develop a scientific consensus on how microwave beams from space‐based solar power (SBSP) satellites will interact with plasma in the ionosphere. Whilst the SBSP concept dates back to the 1970s, it is now gaining traction around the world as a technology that could contribute baseline ...

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...
