Distant Storms Can Affect Seismic Noise Crustal Monitoring

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Using seismic noise interferometry to monitor the Earth's interior relies on continuous seismic wavefields produced by stable, invariant sources. In numerous applications, this condition is relaxed, arguing that secondary scattering effects render the late coda source independent.

Mirror Mode Mediated EMIC Wave Generation in the Magnetosheath

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electromagnetic ion cyclotron (EMIC) waves and mirror modes (MMs), both driven by ion temperature anisotropy, are commonly observed in planetary magnetosheaths. Conventional explanations for their co‐occurrence are largely based on linear instability theory in proton–electron plasmas, which requires comparable growth rates for the EMIC and MM ...

Directional Polarization‐Independent Double‐Zero‐Index Material in a Three‐Dimensional Photonic Crystal With a Fourfold Semi‐Dirac Point

open access: yesNanophotonics, Volume 15, Issue 6, 27 March 2026.
We propose a strategy to realize directional polarization‐independent double‐zero‐index materials within a three‐dimensional photonic crystal which possesses a fourfold semi‐Dirac point. This point exhibits linear dispersions along one direction and quadratic dispersions along perpendicular directions in the momentum space. At the frequency of the semi‐

Turbulence‐Resilient Coherent Receiver Array on CMOS‐Compatible Silicon Photonics for Free Space Optical Communications

open access: yesNanophotonics, Volume 15, Issue 5, 16 March 2026.
A CMOS‐compatible silicon‐photonic 4 × 4 coherent receiver array spatially samples turbulence‐distorted wavefronts and, with maximum‐ratio combining, enables signal recovery. Experimental BPSK tests under moderate turbulence approach theoretical combining efficiency, reducing BER from 1E‐2 to 1E‐15.
