The resonance energy transfer rate between an excited atom and a ground-state one depends on various factors such as the matching between the donor and aceptor wavelengths, location of the atoms, the environment that surrounds them, etc.. In this research, we investigate the interatomic resonance energy transfer rate in the presence of a cylindrical dielectric multi-layer structure using the Green's tensor formalism. The permmittivities of the layers are interchanged periodically between low and high values, so as to creat a photonic band-gap system in the radial direction. We present preliminary results for atoms situated in the same cross section normal to the cylinder axis. The number of layers of the cylinder and the contrast between low and high permittivities are varied to illucidate the effect of the band-gap structure. Furthermore, the results are compared with those for atoms located near a perfectly reflecting cylinder.
