Invisibility cloaks can’t make objects fully invisible in all directions, colors, and polarizations, but Karlsruhe Institute of Technology (KIT) physicists have developed a workaround: an ideal invisibility cloak for diffusive light-scattering media, such as fog.
Their results are published in the journal Science.
In diffusive media, light is scattered by the particles in the medium. Examples are fog, clouds, or frosted glass panes that let the light in, but hide the light source. “This property of light-scattering media can be used to hide objects inside,” says Robert Schittny, first author of the study.
