So, couple this, in terms of the dispersion of energy:
"Our hybrid metamaterial is extremely emissive across the entire atmospheric transmission window (8-13 μm) due to phonon-enhanced Fröhlich resonances of the microspheres."
And this in terms of the absorbtion:
"In the case of large microspheres, modal interference between higher order modes makes the hybrid metamaterial strongly infrared-absorbing."
And finally this in terms of reflectance:
"The hybrid metamaterial strongly reflects solar irradiation when backed with a 200-nm-thick silver thin film prepared by electron beam evaporation... The measured spectral absorptivity (emissivity) of the sample (Fig. 3D) indicates that the 50-μm-thick film reflects ~ 96% solar irradiation..."
