A passive radiative thermostat (PRT) is provided. The PRT comprises a phase-change part comprising a thermochromic phase change material; and a wavelength-selector part designed to create electromagnetic resonances in a wavelength range. The wavelength range may include the visible range, the near-infrared range, or the mid-infrared range. The wavelength-selector part may include an electromagnetic cavity resonator or an electromagnetic plasmonic resonator. Further, the phase-change part may include a thermochromic film; and the wavelength-selector part may include a dielectric spacer.
