Far‐ and Near‐Field Heat Transfer in Transdimensional Plasmonic Film Systems

We compare the confinement-induced nonlocal electromagnetic response model to standard local Drude routinely used in plasmonics. Both of them are applied study heat transfer for transdimensional plasmonic film systems. The former provides greater Woltersdorff length far-field and larger thicknesses at which is dominated by surface plasmons, leading enhanced near-field currents. Our results show that capable making a significant impact on understanding radiative ultrathin films.
