“…These combinations represent different objects. Short and long wires are represented with elements with a radius of 0.05 mm and lengths of 5 and 20 cm, respectively, a pipe is represented with an element of 20‐cm length and 2.5‐mm of radius, and an electric igniter is represented with an element of 5‐cm length and 2.5‐mm radius (Pantoja et al, ). Table shows that the variation in the soils produces a variation higher than 12% in the first resonance frequency.…”

In this paper, we analyze the effect of the soil on the induced current in a buried wire excited by an external field in the ultrahigh frequency range. We use an extended version of the Messier model, which provides the electromagnetic (EM) properties of dispersive soils. Based on comparisons of the Messier model and experimental data, it is verified that this model can be used up to a frequency of about 4 GHz for wet soils. A buried straight wire is used for analyzing the soil effect on the EM coupling with an external plane wave impinging from the air. It is shown that the effects of the soil on the EM response of a wire are mainly (i) to modify its electrical length and (ii) to attenuate the incident wave and, as a consequence, the induced current in the wire. The accuracy of the path decomposition method is assessed. It is shown that this method can be used to estimate with reasonable accuracy the behavior of the induced current. Finally, we study the influence of the frequency-dependence of the soil parameters on the EM coupling to a buried wire. We show that the dispersive nature of the soils affects the spectral content of induced currents in buried wires. Therefore, it can be concluded that the frequency dependence of the soil parameters should not be neglected in EM coupling calculations in the UHF range, especially for low resistivity soils (ρ < 300 Ωm, corresponding to wet soils).

“…9 Michael R. Lambrecht and John J. Pantoja regard the EEDs pin as a non-uniform transmission line to obtain its input impedance, 10 and the coupling current of the pin wire is determined by the matrix equation of the coupling telegraph. 11 Many researchers represented by two-pin wire types all kinds of EEDs have conducted a series of theories and experiment on electromagnetic environment effects, which have made some progress and achievements. However, these efforts have not considered the antenna model structure formed by EEDs caused by the internal structure of the equipment.…”

Concentrating on the two-pin electric explosive devices (EEDs), this paper proposes a coupling model of a V-type antenna according to the typical scenario that the pin wire can present a certain angle. Based on theoretical analysis, numerical simulations are performed to obtain the different angles of antenna patterns, the changes of the reflection coefficients, the gain of coupling current, and the influence law of coupling energy, which are verified by experi-
