Resonant Dyakonov–Shur Magnetoplasmons in Graphene Terahertz Photodetectors

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
Cavity‐confined Dyakonov–Shur plasmons in graphene evolve into magnetoplasmons by an external perpendicular magnetic field. Gate‐tunable THz photocurrent spectroscopy reveals their dispersion over a broad frequency range, uncovering a nonmonotonic behavior in monolayer graphene in contrast to the conventional response of bilayer graphene.

Correction of Non‐Geophysical Errors in SAR Doppler Shift for Ocean Surface Current Retrieval

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Synthetic aperture radar (SAR) data contains Doppler information on ocean surface movement, and the Doppler centroid anomaly (DCA) can be used to quantitatively retrieve ocean surface currents in the line‐of‐sight of radar. However, non‐geophysical errors (NGE) in Doppler information significantly affect retrieval accuracy. Generally, existing
