“…Although the work by Sommerfeld set up the theoretical bases, further research was developed since the publication of his first paper on the subject [Sommerfeld, 1909] in order to investigate the application of the theory to several propagation and radiation problems of practical interest [Norton, 1937;Longman, 1956;Novikov and Makarov, 1961;Wait, 1964;Baños, 1966]. With the coming of numerical analysis techniques, an ever-growing attention was paid to the development of methods for the evaluation of both the Green functions and their integrals on the scattering geometries [Siegel and King, 1970;Bubenik, 1977;Mittra et al, 1979;Rahmat-Samii et al, 1981;Maclean and Wu, 1993;Chew, 2000a, 2000b].…”

“…which is the form used by Norton [1937] for a homogeneous half-space, which, in the present context, corresponds to setting the coating thickness L equal to zero. In such a case the phase of the normalized surface impedance A is never less than -45 ø, in which case the phase angle of p is never negative.…”

“…The radiation of antennas at the interface of media has been the subject of numerous studies to date [1][2][3][4][5][6][7][8][9][10][11][12][13]. The scenario of interest is a classic problem in electromagnetics dating back to the work of Sommerfeld in 1909, investigating the radiation of a source above a lossy halfspace [1].…”

“…Other effects such as subsurface peaking was also explored by the same authors in [14]. Such studies have been intended for various applications such as Ground Penetrating Radar [15,16], antennas for communication above earth or under water [2,13], antennas on semiconductors [9] or above dielectrics for imaging [12], to only name a few.…”
