Passive intermodulation model and experimental verification of cascaded microwave devices
, 2017 Passive intermodulation (PIM) is a complex problem in high-power microwave devices and satellite communications. In this paper, an effective calculation method is proposed for predicting PIM power levels of the cascaded microwave devices.

Advanced Energy Materials, EarlyView.Schematic comparison of optimized F–NiFe–LDH and conventional NiFe–LDH electrodes during alkaline natural seawater oxygen evolution. The synergistic (poly)CM protective layer and fluoride‐mediated passivation suppress metal leaching, mitigate chloride‐induced corrosion, and regulate surface reconstruction, preserving catalyst integrity beyond 1000 h ...

Target detection using microwave irradiances from natural sources: A passive, local and global surveillance system [PDF]
, 1984 Detection of metal objects on or near the Earth's surface was investigated using existing, passive, microwave sensors operating from Earth orbit. The range equations are derived from basic microwave principles and theories and the expressions are given ...

Autonomous Charging and Battery Swapping for Unmanned Aerial Vehicles: A Review
Advanced Intelligent Systems, EarlyView.This review evaluates major autonomous charging and battery swapping methods for unmanned aerial vehicles (UAVs) against a single question: how close each is to sustained unattended operation. Rather than ranking them by charging performance, it identifies the limitation that most restricts each method, and briefly outlines the supporting technologies ...
