asteroza + reradiation   3

Nanoscale Research Letters | Full text | Tailoring photonic metamaterial resonances for thermal radiation
This seems to use the same kind of tricks as those luminescent solar concentrator plates, that internally reflect captured light and convert the frequency internally to retransmit to edge PV modules. Just shifting down to IR. The interesting bit is the prevention of reradiation through the top surface, which provides the potential for solar thermal power generation without concentrating mirrors using not well aligned surfaces of panels manufactured using chip fabrication techniques.
