The Randall-Sundrum metric is modified by adding a perturbation to the extra dimension metric component. In this paper we derive the energy-momentum tensor that represents the perturbation to the original Randall-Sundrum metric and show the similarities and differences between the disturbed Randall-Sundrum model and the original one. In adition, this paper investigates the localization of <br /> <br /> <br /> scalar and vector fields. The localization properties of the disturbed Randall-Sundrum model are better than that of the original Randall-Sundrum model. Both massless dan massive modes of scalar fields are localized for a positive parameter <br /> <br /> <br /> of the warp factor if the perturbation is proportional to the extra dimension coordinate. Massless vector fields in the other hand are localized irrespective of the warp factor parameter.
