Conversion of the UTD Method to an Exact Method at All Frequencies for 2-D Conducting Half-Plane Problems

In addition to two recently discovered series, we discover a new asymptotic series for the exact solution of two-dimensional conducting half-plane problems. These series are compared with the ones used in the conventional uniform theory of diffraction (UTD) method solutions of the problem. By attaching some coefficients, which are not complex, to the terms of those series we convert the UTD method to an exact method at all frequencies, including low ones, regarding the given problem type. Schemes for calculations of these series with 7 digits of accuracy or 2 digits of accuracy for high-speed calculations are described.
