- We have numerically implemented a perturbation series for the scattered electromagnetic fields above rough
surfaces, due to Greffet, allowing us to evaluate the local density of states to second order in the surface profile
function.We present typical results for thermal near fields of surfaces with regular nanostructures, investigating
the relative magnitude of the contributions appearing in successive orders. The method is then employed for
estimating the resolution limit of an idealized near-field scanning thermal microscope.
