Penketh et al. develop an approach for mapping the frequency response of thousands of meta-atoms in a microwave metasurface simultaneously, leading to the formation of detailed hyperspectral images. The approach—applicable to a wide range of metasurfaces - may overcome fabrication challenges for translation of such metasurfaces to real-world devices.
