Abstract: We present several versions of Regularized Combined Field Integral Equation (CFIER) formulations for the solution of two and three dimensional frequency domain scattering problems with various kinds of boundary conditions. These formulations are based on suitable approximations to Dirichlet-to-Neuman operators and can be shown to be well posed, under certain assumptions on the regularity of the scatterers. For a wide variety of scatterers, solvers based on these formulations outperform solvers based on the classical Combined Field Integral Equations.
