DOI: 10.1109/tap.2025.3560764
Abstract: Reconfigurable metasurfaces are among the key technologies for agile beam modulation. However, conventional reflective or transmissive reconfigurable metasurfaces require external feed sources and have an increased overall system profile. In this communication, a Ka-band cross-shaped… read more here.

DOI: 10.1111/jmi.13406
Abstract: High‐quality transmission electron microscopy (TEM) specimens are critical for high‐resolution imaging and conducting electron energy loss spectroscopy (EELS) analysis. However, fabricating cross‐sectional TEM specimens with large, thin, and low‐damage regions remains challenging, particularly with conventional… read more here.
