N2 - Scattering by semi-infinite cone obstacles is a fundamental canonical problem in wave theory [1]-[2]. The formal exact solution to this problem is given by an infinite series of conical harmonics, yet the practical applicability of this solution is limited due to its slow convergence. Furthermore, this solution does not convey explicitly the physics of the diffraction problem, and in particular, the conical harmonics need to be calculated for each cone-angle by finding the roots of the characteristic equation. Nevertheless, this solution can be used to investigate the diffraction physics numerically by calculating the scattered field due to localized incident beams that hit at or near the tip, as has been done recently in [3]-[4] where it has been used to solve the problem of complex-source beam (CSB) diffraction by a cone.
