The dyadic Green's function for electric and magnetic fields of a point current source radiating in close vicinity of a perfectly electric conducting wedge (PEC) has been derived through two independent means by Pearson and by Buyukdura, Goad, and Kouyoumjian. Asymptotically, a so-called the edge wave may be identified when the source and the observation points are in proximity to the edge but widely separated along the edge, and has become part of the canonical problems in asymptotic diffraction theory. Both of the formulations indicated lead to identical asymptotic results. To corroborate the existence of edge waves, a series of measurements has been performed and the measured data are fit to a model based on the asymptotic results. The fit of the data supports the asymptotic form.
