Abstract
In this work, the fast physical optics (FPO) method is proposed to calculate the scattered fields from the coated scatterers. Different from the plane discretization, the quadratic patches are used to model the surface of the scatterers. Hence the number of the meshes would reduce greatly. With adopting the Lagrange interpolation and the closed-form formulation, the scattered fields could be represented as the analytical formulations. Numerical results demonstrate the accuracy and the efficiency of this method.
