Claim Text:
1. An isotropic sensor of magnetic field and electric field, which comprises three sensor units, each sensor unit comprising: a lead wire winding surrounded by a conducting screen, the conducting screen being interrupted in two first zones diametrically opposite, in such a way that two independent screen segments are defined, and with each screen segment comprising two ends; first terminals for measuring the currents induced by the magnetic field in the lead wire winding, the first terminals being provided in one of said two first zones; second terminals for measuring the voltage induced in the screen by the electric field, the second terminals being provided in the other one of said two first zones; wherein the two ends of each screen segment in the two first zones are connected two by two by means of conductors; and wherein the conducting screen comprises two second zones of interruption disposed at a halfway point of each one of the screen segments in such a way that it is possible to measure at high frequencies simultaneously, independently and with precision, both the magnetic field on the basis of the measurement of the first terminals of the winding, and the electric field on the basis of the measurement of the difference in potential between the two screen segments.
