Method of iterative Physical Optics for the estimation of the scattering behavior of large layered dielectric bodies

The correct estimation of the scattering behavior of large dielectric objects is a particularly challenging task and well suited for the application of the Method of Physical Optics (PO). In this paper we propose the application of an iterative extension of the physical optics approach to the estimation of the scattering behavior of large layered dielectric bodies. With a suitable truncation and an efficient implementation layered structures can be modeled and simulated sufficiently accurate by the proposed method.
