On the excitation of the Zenneck surface wave over the ground at 10 MHz

Excitation de l’onde de Zenneck au-dessus du sol a 10 MHz

Abstract

Using a planar earth model the infinite vertical aperture with a Zenneck wave variation is found to excite only the Zenneck wave with no radiation field. The finite vertical aperture excites a field which is similar to the Zenneck wave near the aperture but resembles the usual ground wave at large distances. Numerical results for various aperture heights are given for a frequency of 10 MHz for a homogeneous ground path.

Analyse

Dans l’hypothèse d’une terre plane, une antenne verticale infinie dont la répartition du champ dans l’ouverture est celle d’une onde de Zenneck excite uniquement cette onde de surface sans champ rayonné. Une antenne de dimension finie excite un champ qui ressemble à celui de l’onde de Zenneck près de l’ouverture, mais se rapproche de l’onde de sol classique à grande distance. Des résultats numériques sont donnés pour diverses hauteurs d’antenne à la fréquence 10 MHz en présence d’un sol homogène le long du trajet radioélectrique.
