What is it about?
The effects of pores on the emitter performance have not been studied well due to the complexity. In this letter, we reveal the effects by analyzing the thermal emission spectra of garnet (Yb3Ga5O12) emitters by using a Kubelka-Munk-(KM) like two-flux model. We demonstrate that the emitter performance can be maximized by optimizing the porosity.
