Scattering from corner reflectors; a hybrid approach

The scattered fields from dihedral and trihedral corner reflectors are computed using a hybrid method. This hybrid method employs the UTD (universal geometrical theory of diffraction) to compute the scattered fields from the corner reflector, on a surface (S) enclosing it. Then, these fields are used to find the equivalent electric and magnetic currents on S. These currents are then used in radiation integrals to find the scattered fields from the corner reflector. Good agreement is shown with moment-method results.<
