Capacitive resistivity (CR) is an emerging geophysical technique designed to extend the scope of the conventional methodology of DC resistivity to environments where galvanic coupling is notoriously difficult to achieve, for example across engineered structures (roads, pavements), hard rock, dry soil or frozen ground. Conceptually, CR is based on a four-point array capacitively coupled to the ground. Under A parametric study of the complex quasi-static transfer impedance reveals the existence of a restricted range of practical parameters that permits successful operation of CR instruments at low induction numbers. Theory predicts that emulation of the DC measurement is compromised if low-induction-number operation is not maintained throughout a survey area, for example in a zone of high conductivity.

“…It is however possible to determine both σ and ε, by measuring both the in-phase and the quadrature (out of phase) components of the voltage (Tabbagh et al, 1993). 3) In order to avoid induction effects that would drastically reduce the depth to which materials could be measured (Benderitter et al, 1994;Tabbagh and Panissod, 2000) the induction number IN = σμωL 2 must verify IN ≪ 1, µ being the magnetic permeability and L the characteristic length of the instrument. When L lies in the range between 0.1 and 0.2 m, this last condition is easily verified.…”

“…La limite en fréquence peut être fixée (Benderitter et al, 1994 ;Tabbagh et Panissod, 2000) à partir du nombre d'induction qui doit rester inférieur à 0,1 envi ron. Ce nombre d'induction compare la taille du qua dripôle à la profondeur de pénétration caractérisant l'effet de peau (c'est-à-dire l'atténuation du signal avec la profondeur, et la décroissance de la profondeur d'investigation avec la fréquence du signal).…”

To explore the first ten metres, the electrostatic method can replace the DC electrical method to image the structure of the ground with the same interpretation methods. Three examples are presented hereafter. In the first, one attempted to characterise the medium in which a micro-tunnel had to be drilled. In the second one looks under the Bastia cathedral pavement, for the preceding medieval church remains. In the third, the path of the antique wall, a major feature of the global organisation of the city of Alexandria, was located under the streets.
