A modification of the Randall-Sundrum metric model in the form of conformally flat metric was proposed some years ago. The proposed model shows better localization properties than the original Randall-Sundrum model. However, this new model still does not meet the expectation that all fundamental fields can be localized for one type of warp factor, e.g. for a decreasing warp factor. In this research we propose to add a factor ( f(r) ) in the extra coordinate part of the above modified Randall-Sundrum metric and derive conditions for localization for scalar and vector fields. ( r ) is the extra coordinate. We then look for some functions ( f(r) ) that fulfill the localization conditions for both scalar and vector fields. Examples of the function ( f(r) ) under investigation are ( exp(Ar) ), ( exp(Ar + Br^2) ), ( exp(A/r) ), ( Ar ), ( Ar + Br^2 ), and ( sinh Ar ). When the expected function is found we then check whether our model will also localize spinor fields or not.
