“…However, severe aerial coupling between cables with this arrangement made impossible to obtain reliable measurements. Signal leakage is not negligible in RG-58 cable for this frequency range [10] since extremely weak signals are measured. Moreover, coupling between coaxial cables is higher at low frequencies and long cables.…”

Abstract-Shallow seawaters are problematic for acoustic and optical communications. Sensor networks based on electromagnetic (EM) communications are evaluated in this environment. In order to characterize the subaquatic channel, several measurement systems have been designed, built and tested in the sea obtaining very reliable results. Experiments carried out with dipoles and loop antennas showed serious disagreement with the state of the art, especially when dipole antennas are used. Dipoles performance was poor while magnetic loops showed relevant results. Measurement system is described in detail and real attenuation of the subaquatic channel is obtained for several distances and antennas. Finally, measured and simulated results are compared with good agreement.

“…There are many models for transfer impedance that compare well with measurement [2]. In this work we have used the model proposed by Kley [4] but other models have been found to provide similar results.…”

“…Engineers need to be aware of when and to what degree this occurs so that system EMC compliance and signal integrity is assured. Many accurate models for braided cable transfer impedance and admittance have been proposed [1,2], which is the usual measure of the shielding properties of the cables. When these models of transfer impedance and admittance are combined with a circuit description of the coupling path between cables then this also provides an accurate measure of the cable coupling between the cables [3].…”

− In this paper the crosstalk between two parallel coaxial cables is investigated. It is shown that the degree of coupling is strongly effected by the geometry of the system. In many practical situations the geometry of the cable routing is ill-defined so that an exact deterministic solution is not possible or helpful. A simple solution based on the first resonant frequency is proposed which can also be used to provide some statistical analysis of the possible degree of cable coupling.

“…For more than two cables, however, the coupling model is complicated by the mutual couplings between the receptor circuits. Other efficient numerical techniques exist for crosstalk prediction of multicoaxial cable bundle (MCCB) systems [2] by using the transfer impedance [10], modal decomposition [11] and eigenvalue method [12]. However, these methods all have the disadvantage of high memory requirements and long simulation time.…”

Abstract-In this work, a new efficient simplification method is proposed for crosstalk prediction of multicoaxial cable bundles (MCCB). The purpose of the new simplification method is to reduce the simulation time by reducing the complexity of the complete cable bundle model. A modified five-step procedure is established to define the electrical and geometrical characteristics of the reduced cable bundle by making the outer and inner conductor of the coaxial cable participate in the equivalence procedure respectively. After a short presentation of the MCCB coupling problem, the theory fundamentals of the new simplification method and numerical simulations performed on a simple MCCB are presented to demonstrate the efficiency and the advantages of the new simplification method.
