Abstract
An explanation to the experimental results reported by Monstein and Wesley (Europhys. Lett., 59 (2002) 514), who claimed they had discovered “longitudinal electromagnetic waves”, are explained by means of the classical electromagnetic theory. It is proved that the cited authors detected classical TEM waves emitted by currents flowing in the Earth and launched by the ball antenna used in the experiment. A kind of plasma theory is used to describe the behavior of charges in the Earth and the predictions it yields appear to agree with the experiment much better than the original ones presented by Monstein and Wesley.
