Related Paper: Assessment of Rydberg Atoms for Wideband Electric Field Sensing https://arxiv.org/abs/1910.00646 https://arxiv.org/abs/1910.00646 Mentally replace the word "Electric Field" with RF when you're reading it, and you'll get it. Also, according to the paper at least, in theory, laser interferometers can be used to sense RF... which leads to the idea that perhaps the entire RF spectrum, viewed as a single point in time snapshot, looks like an interference pattern of all sorts of waves at all sorts of wavelengths... From a series of those then, Fourier Transforms, ran over the whole dataset, could be used to extract individual waves... Also, there's some kind of vague relationship here with holograms too, because holograms are in effect, interference patterns of two beams of laser light...
