Abstract

A simple scheme which is free of the decoupling problem is used with unstructured grids to calculate scattering off airfoils. Standard numerical techniques with equal order interpolation and no staggering for both the electric and the magnetic field are employed, and some preliminary results are presented. Scattering of plane waves off cylinders and airfoils was simulated. Contours, current density, and radar cross section were generated after 7.96 cycles.<>
