“…The dependency ∼1/r is exactly the same as for the case of free space (spherical-type wave in vacuum) while the ∼1/r 2 decay is redolent of the Norton wave arising in radio transmission at the Earth's surface 19 and of radiation by holes in metals. 20 Analytical form of the Green's dyadic of free space for z = 0.…”

“…Instead, the asymptotic field arises from the kink in the angular spectrum (see Fig. 2), and is reminiscent of the Norton wave found in the studies of radio transmission at the Earth's surface 19 and of radiation by holes in metals. 20 This asymptotic field decays as r −2 and is predominantly TM polarized.…”

“…This field component presents the two-dimensional analog of the Norton waves (NW) discovered theoretically almost a century ago by Norton,22 when analyzing the radiation of radio waves by a point dipole placed over the Earth's surface (represented by a lossy dielectric).…”

“…The solution by Sommerfeld is very complicated and requires advanced mathematical skills. Therefore, Norton developed simplified, easier to use formulas in 1936 [15]. We quote here from his introduction ''Since that time (Sommerfeld 0 s time, inserted by the authors) many other investigators have obtained similar solutions of the problem in various ways.…”
