Broadband Mid-Wave Infrared Imaging Enabled by All-Silicon Hyperboloid Metalens.

arXiv:2610.29841v1 Announce Type: cross Abstract: The mid-wave infrared (MWIR, 3-5 microns) is indispensable for thermal sensing, gas detection, long-range imaging, and free-space optical communications. Meta-optics offer a compact, lightweight, and potentiall
