Fringe Currents Evaluation on a Perfectly Conducting Wedge Illuminated by an Elementary Dipole

The field generated by an elementary dipole in presence of a perfectly conducting wedge can be expressed analytically through a double infinite series. The series convergence gets critical when the observation point and the source are close to each other. In this contribution an improvement of that analytic solution, attained by extracting Green's function singularity, is presented, speeding up series convergence and allowing efficient computation of fringe currents, which are the corrective term, taking into account diffraction, to physical optics current.
