A hybrid technique for combining the Method of Moments with the Geometrical Theory of Diffraction in the frequency domain is described. Typical results for a monopole near a perfectly conducting wedge and for a monopole at the center of a circular disc are presented. It is shown that, since the Method of Moments characterizes only a portion of the problem, it is computationally economical to generate sufficient frequency domain data to obtain time domain solutions via the Fast Fourier Transform FFT. To illustrate the method, the problem of a monopole at the center of a disc is considered for several cases, including a step input, a Gaussian pulse input and a Gaussian pulse plane wave incident upon the monopole disc structure from various aspect angles.
