Claim 9:
10. An apparatus comprising:
a radiative cooling device having
an ultraviolet reflector comprising a multi-layer stack including a plurality of material layers to prohibit coupling of incoming electromagnetic radiation to a portion of the radiative cooling device; and
a thermal emitter to generate electromagnetic emissions from the radiative cooling device; and

a heat exchanger to exchange heat between the radiative cooling device and a load, wherein the multi-layer stack includes:
a first set of layers comprising layers of TiO2 having a thickness of 25 nm and layers of MgF2 having a thickness of 35 nm;
a second set of layers comprising layers of TiO2 having a thickness of 50 nm and layers of MgF2 having a thickness of 70 nm; and
a third set of layers comprising layers of TiO2 having a thickness of 75 nm and layers of MgF2 having a thickness of 105 nm.
