Near-Field Radiative Heat Transfer in the Dual Nanoscale Regime between Polaritonic Membranes
Abstract
The enhancement and attenuation of near-field radiative heat transfer between polaritonic SiC, SiN, and SiO_{2} subwavelength membranes is analyzed. Fluctuational electrodynamics simulations combined with a modal analysis show that all membranes support corner and edge modes, which can induce a large 5.1-fold enhancement for SiC and a 2.1-fold attenuation for SiO_{2} of the heat transfer coefficient with respect to that between infinite surfaces. The enhancement or attenuation is directly related to material losses, which reduce the density of available electromagnetic states between the membranes.
