A new 2D fast physical optics method

A new fast physical optics method is introduced for computing backscattered fields at high frequencies. A stokes-type method is presented for computing highly oscillatory integrals a over simplex from extremal points and the stationary phase points of the simplex. The computational cost of the scattering integral behaves as O(1) with frequency
