An Ultra‐Sub‐Wavelength Microwave Polarization Switching Antenna for Covert Communication Implemented With Directed Surface Acoustic Waves in an Artificial Multiferroic Magnonic Crystal

Advanced Materials Technologies, EarlyView.
A surface acoustic wave (SAW) launched in a two‐dimensional periodic array of magnetostrctive nanomagnets on a piezoelectric substrate excites spin waves in the nanomagnets which radiate electromagnetic waves in space. The polarization of the emitted beam in particular directions and at particular frequencies can be switched between horizontal and ...

Particle Size Matters – Impact of Particle Size and Crucible Geometry on Sublimation Behavior of Formamidinium Iodide

Advanced Materials Technologies, EarlyView.
FAI precursor particle size and sublimation crucible geometry critically determine vapor flux directionality and deposition uniformity in thermal sublimation processes. Conical crucibles exhibit particle‐size‐dependent beam focusing, while cylindrical crucibles show a much more homogeneous deposition due to de‐focusing effects of the emitted vapor flux.

Mechanoluminescence from Visible to Second Near‐Infrared Region Based on Sr3Sn2O7 Matrix

Advanced Optical Materials, EarlyView.
This study reports a defect‐tolerant derived layered perovskite Sr3Sn2O7: Ln3+ system exhibiting exceptional multimodal luminescence across 450–1600 nm. The material integrates photoluminescence (PL), persistent luminescence (PersL), X‐ray excited luminescence (XEL), and intense mechanoluminescence (ML) with 30‐fold higher ML intensity than PersL for ...
