1. A method for radiative cooling of an object positioned thereunder, comprising:
providing a fabric including one or more fibers extending for a length in a longitudinal direction; and
introducing a plurality of void structures to each of the one or more fibers, wherein the plurality of void structures are configured to at least a portion of electromagnetic radiation received thereon in a transverse direction of the one or more fibers, wherein the plurality of void structures are configured to propagate the electromagnetic radiation in a longitudinal direction of the one or more fibers to thereby radiatively cool the object, wherein the one or more fibers are configured to have the plurality of void structures in a density between about 2.2 voids/μm2 and about 17 voids/μm2 to enhance a solar reflectivity in visible and near-infrared spectrums.
