Query: Anomalous near-field heat transfer between a cylinder and a perforated
  surface   We predict that the radiative heat-transfer rate between a cylinder and a
perforated surface depends non-monotonically on their separation. This
anomalous behavior, which arises due to near-field effects, is explained using
a heuristic model based on the interaction of a dipole with a plate. We show
that nonmonotonicity depends not only on geometry and temperature but also on
material dispersion - for micron and submicron objects, nonmonotonicity is
present in polar dielectrics but absent in metals with small skin depths.
