Abstract

For solving integral equations in electromagnetic scattering by using iterative methods

the convergence rate depends on the accuracy of the initial solution. When handling the electromagnetic scattering problems with multiple incident directions

a new extrapolation scheme based on minimization of error can produce accurate initial solution

which speeds up the convergence rate considerably. The examples of scattering by a conducting cylinder and by a dielectric body verify the efficiency of our new procedure.
