Abstract
Ultra‐Broadband, High Efficiency Polarized Beam Splitter Metagrating
In article number 2201227, Hui‐Hsin Hsiao, Richard E. Muller, Dejian Fu, and co‐workers demonstrate a polarized beam splitter metagrating that enables simultaneous measurement of four spatialspectral‐ polarimetric images with an efficiency of 70% and a polarimetric contrast greater than 0.996 in the entire near‐infrared oxygen bands, which will be integrated into NASA's high‐resolution multiplespecies atmospheric profiler instrument for vertical profiling of global aerosols.
