Abstract
A new 3D fast physical optics method is introduced for computing backscattered fields at high frequencies of PEC surfaces. A stokes-type method combined with approximation by error type integrals is presented for computing highly oscillatory integrals over surfaces from extremal points and stationary phase points of the surface. The computational cost of the scattering integral behaves as O(1) with frequency
