In this paper the finite-difference time-domain (FDTD) method is generalized to include the accurate modeling of curved surfaces. This generalization, the contour path (CP) method, accurately models the illumination of bodies with curved surfaces, yet retains the ability to model corners and edges. CP modeling of two-dimensional electromagnetic wave scattering from objects of various shapes and compositions is presented.
