Abstract:
The well-known “Sommerfeld radiation problem” of a small -Hertzian- vertical dipole above
flat lossy ground is reconsidered. The problem is examined in the spectral domain, through which it is
proved to yield relatively simple integral expressions for the received Electromagnetic (EM) field. Then,
using the Saddle Point method, novel analytical expressions for the scattered EM field are obtained,
including sliding observation angles. As a result, a closed form solution for the subject matter is
provided. Also, the necessary conditions for the emergence of the so-called Surface Wave are discussed
as well. A complete mathematical formulation is presented, with detailed derivations where necessary
