Advanced Photonics Research, Volume 7, Issue 3, March 2026.Terahertz microscale silicon waveguides can be wholly unclad, making it possible to interact with guided waves contactlessly via evanescent fields. We exploit this with conductive walls that enforce a movable field‐null upon modal fields, enabling tunable dispersion and cutoff similar to a fiber squeezer, albeit without physical contact.

Software Defined Radio Implementation of Carrier and Timing Synchronization for Distributed Arrays
, 2018 The communication range of wireless networks can be greatly improved by using distributed beamforming from a set of independent radio nodes. One of the key challenges in establishing a beamformed communication link from separate radios is achieving ...

Small Science, Volume 6, Issue 3, March 2026.Photochemical metal–organic decomposition (PMOD) enables scalable patterning of lithium niobate (LN) metasurfaces under ambient conditions, eliminating the need for cleanrooms or harsh etching. This bottom‐up approach produces complex, diverse, and size‐tunable polycrystalline LN patterns.

Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code.

Global Eddy Subduction Carbon Pump From Argo Floats
Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.Abstract The eddy subduction pump, part of the biological pump, transports carbon‐rich surface filaments downward via kilometer‐scale turbulence in frontal regions, over days to weeks. Because of its spatial and temporal scales, this pump has been challenging to observe and quantify.
