PO/PTD ray tracing for arbitrary metallic and dielectric objects

A new, efficient and very accurate simulation approach based on a hybrid ray tracing technique is presented. The unique combination of a ray-density normalization (RDN) with Physical Optics (PO) and the Physical Theory of Diffraction (PTD) makes the algorithm almost universally applicable to arbitrary simulations of large and complex objects. This paper gives an overview on simulation results obtained at highly complex objects and focuses on the implementation of PO for dielectric objects.
