Abstract

A comparison between two forward solving methods, recursive T- matrix and FDTD, is presented. The strengths and weaknesses of both methods are discussed. The recursive T-matrix method is a fast solver that is well suited to solutions in homogeneous media where the scatterers are bodies of rotation. The FDTD method is best suited to complicated and realistic problems involving inhomogeneities, rough surface interfaces and irregular shaped scatterers. Numeric results from both methods are presented.
