We numerically analyzed the spontaneous emission at near-field and determined radiative heat flux at nano-scale in order to investigate the impact of geometric variations and material selection in these systems. Our findings suggest that these metasurfaces which support phononic surface waves, can be used to tailor radiative heat transfer at nano-scale in the atmospheric transparency window (8-13 mu m) within the infrared regime.enginfo:eu-repo/semantics/openAccessConference paper10731000449787600006Nano-scale radiative coolingPhononic metasurfacesBiomimicry designsMorpho butterflyFinite difference time domain method2-s2.0-85055330293
