Reconfigurable Giant Nonreciprocity at Near‐Normal Incidence via Phase‐Change Magneto‐Optical Metagratings

open access: yesLaser &Photonics Reviews, Volume 20, Issue 18, 18 September 2026.
A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

open access: yesMetalMat, Volume 3, Issue 3, September 2026.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

Single‐shot third‐harmonic spectral diagnostics for tender X‐ray FEL pulses using a bent‐crystal spectrometer

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 5, Page 1486-1494, September 2026.
Third‐harmonic spectral monitoring with an existing bent‐crystal spectrometer provides single‐shot bandwidth diagnostics and real‐time machine tuning for tender X‐ray free‐electron laser operation, and can be made non‐invasive when combined with a suitable beam‐sampling grating.The tender X‐ray (2.0–4.0 keV) region provides access to the K‐edges of ...

Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling [PDF]

open access: yesRadioengineering, 2016
A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters.

Microstrip ring resonator and dispersion measurement on microstrip lines

open access: yesElectronics Letters, 1971
A theory is described which takes into account the curvature of the microstrip ring resonator. This curvature is shown to have a large influence on dispersion measurements on microstrip lines with small impedences.
