Uniform geometrical theory of diffraction (UTD) is often used for computing electromagnetic propagation over obstacles at radio or microwave frequencies. The UTD method has been successfully applied to the problem of wedge diffraction, yielding very accurate solution. This paper compares UTD method with parabolic wave equation (PF) method. Details of the comparison are presented.
