Using full‐waveform techniques to understand lysimeter‐induced effects on ground penetrating radar measurements

Vadose Zone Journal, Volume 25, Issue 6, November/December 2026.
Abstract Lysimeters are widely used to investigate soil‐plant‐atmosphere interactions and to assess the impact of management practices on water and nutrient fluxes. These interactions and fluxes are strongly impacted by local scale variability in soil water content and soil hydraulic properties. However, centimeter‐scale imaging of subsurface processes

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Detection and Analysis of an Upward Jet‐Like Electrical Discharge Intercepting a High‐Altitude Research Aircraft

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

Scalable Multi‐Target Illusion via a Segmented Spatiotemporal Metasurface

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
An electromagnetic kaleidoscope is realized with a segmented spatiotemporal metasurface that transforms one physical aperture into multiple independently controlled false targets. Parallel‐sequence spectral translation codes apparent range and velocity, while segment allocation regulates echo amplitude. Experiments at 5 GHz generate two to five targets

Target models and waveform design for detection in MIMO radar

, 2014
In this paper, we propose a general target model for multiple-input multiple-output (MIMO) radar. Two types of targets are presented. For each type of target, we develop a corresponding optimum waveform designing method to optimize detection performance.
