Query: Geometric effect on near-field heat transfer analysis using efficient
  graphene and nanotube models   Following the recent research enthusiasm on the effect of geometry on
near-field heat transfer (NFHT) enhancement, we present an analysis based on
simplified yet highly efficient graphene and nanotube models. Two geometries
are considered: that of two parallel infinite "graphene" surfaces and that of a
one-dimensional infinite "nanotube" line in parallel with an infinite surface.
Due to its symmetry, the former is in principal simpler to analyze and even so,
earlier works suggested that the application of a full model in this problem
still demands heavy computations. Among other findings, our simplified
computation - having successfully replicated the results of relevant earlier
works - suggests a sharper NFHT enhancement dependence on distance for the
line-surface system, namely $J\sim d^{-5.1}$ as compared to $J\sim d^{-2.2}$
for the parallel surface. Such comparisons together with applications of our
efficient approach would be the important first steps in the attempt to find a
general rule describing geometric dependence of NFHT.
