  The evaluation of the absorption cross section of a massless scalar field
propagating on a non-extremal black D3-brane smeared on a circle is considered.
The solution to the scalar field equation of motion at high temperature is
obtained in terms of the parameters $\lambda=3\omega/4\pi T$ and $k$, which
denote the frequency and the momentum along the circle respectively while $T$
denotes the temperature of the black brane. Based on a perturbative scheme,
higher order temperature corrections to the scalar absorption cross section are
computed. Further, interesting analogies with the cross section of known black
branes solutions are discussed.
