The passive radiant cooling layer includes at least two layers among a first emission layer having a high emissivity in a first band relative to a band outside the first band, a second emission layer having a high emissivity in a second band, which is included in the first band and narrower than the first band, relative to a band outside the second band, and a reflection layer having a high reflectivity in a third band, which is a shorter wavelength than the first band, relative to a band outside the third band.

An optical combiner includes a first layer with a periodic arrangement of structures of a material with a first refractive index. A second layer overlies the structures on the first layer, and the second layer includes a material with a second refractive index. A difference between the first refractive index and the second refractive index, measured at 587.5 nm, is less than 1.5. The periodic arrangement of structures is configured such that the optical combiner produces, for an input signal incident on the first layer from air at an oblique elevation angle of greater than 20°, an output signal with three reflection peaks, each reflection peak having an average reflection of greater than 50% within a ±3° range of the elevation angle.

A spectral filter may include a plurality of filter arrays each including a plurality of unit filters having different center wavelengths from each other. Each of the plurality of unit filters may include a first metal reflection layer and a second metal reflection layer which are disposed to be apart from each other; a cavity including a first pattern and being arranged between the first metal reflection layer and the second metal reflection layer; and a lower pattern film being disposed under the first metal reflection layer and including a second pattern. In unit filters having a same center wavelength in each of the plurality of unit filters corresponding to the plurality of filter arrays, the first pattern of the cavity and the second pattern of the lower pattern film may vary according to a position of the unit filters.
