The reflection/refraction of these materials also have to cover a broad range of wavelengths since, once the craft is moving fast enough, the incoming photons will be red-shifted.

Researchers have uncovered the magnetic properties and underlying mechanisms of a novel magnet using advanced optical ...

Indeed, the "voids" the water droplets leave behind after evaporating can reflect up to 99.6-percent of light, the researchers found, across the IR, visible, and UV spectrums.
