The scattering problem from the surfaces is introduced by method of Modified Theory of Physical Optics (MTPO). The method is based on the physical optics (PO) current, on the scaterers' and aperture surfaces, which assist in finding the integral equation and the evaluation is achieved asymptotically with the stationary phase method. The comparisons, on various surfaces, prove the agreement of the MTPO with respect to the exact solution of Helmholtz equation. MTPO can be applied to calculate not only the reflected fields but also to calculate edge diffraction fields of various surfaces such as perfectly electrically conducting (PEC), impedance and black surfaces.
