Advanced Fade Mitigation Techniques for Q/V Band SATCOM Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Adaptive fade mitigation techniques, such as smart gateway diversity (SGD), are essential in addressing atmospheric fading affecting the operation of high throughput and very high throughput satellite systems at Ka‐band and beyond. Specifically, the Q/V‐band, offering up to 5 GHz of available spectrum, is very attractive for future high data ...

Large Unsaturated Magnetoresistance in Gated MoS2 Flakes

Small, EarlyView.
Magnetotransport investigation of layered MoS2 crystals in field‐effect devices reveals strong dependence on thickness and carrier density. Monolayer MoS2 exhibits the highest magnetoresistance of 680%. A combination of density functional theory and Boltzmann transport equation simulations shows that band transport is not causing the magnetic behavior,
