Single-Conductor Strip Leaky-Wave Antenna

, 2020
In this case, the normalized phase constant is very close to 1 and this results in a fixed main-beam radiation pattern in the end-fire direction. This leaky-wave antenna with only a single rectangle stripline of length 110 mm can achieve the same broad ...

Closed‐Loop Solid‐State Synthesis Planning for Materials Discovery With Large Language Models

Advanced Materials, EarlyView.
Leveraging literature data, we build a large‐language‐model‐driven workflow that extracts synthesis steps from 4407 papers, retrieves similar precedents, and generates candidate solid‐state synthesis recipes. The system benchmarks against ground‐truth and then operates in a closed loop with experiments to synthesize oxy‐selenide electrolyte materials ...

Electromagnetic inspired acoustic leaky-wave antenna [PDF]

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous ...

Near-Field Focusing With Bi-Directionally Fed Frequency-Scanned Antennas for Proximity Sensing

IEEE Open Journal of Antennas and Propagation
The application of one-dimensional bi-directional fed frequency-scanning leaky-wave antennas for proximity sensing is studied in this work. Using the two opposite ports of a microstrip antenna, a near-field focused radiation pattern which varies with ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...
