The iterative formulation is constructed based on the principle of Born approximation method due to the difficulty in using direct numerical resolution which is as a result of implicit nature of the function. The computed field value, φ through the thin film with variation of the propagation distance was analyzed within the ultraviolet, visible and near-infrared of electromagnetic wave.]]>Fleck, J.A., J.R.
