Modèles analytiques originaux pour la détermination des paramètres linéiques des lignes et câbles multifilaires parcourus par des signaux large bande

Abstract : The coupling of incident fields (plan wave; lightning stroke; nuclear electromagnetic pulse; current injection; ...) with lines or cables gives rise to over voltage which can damage electrical and electronic apparatus connected at the ends of these lines or cables. Accurate line or cable models are needed to solve these problems. Most of existing models suppose lossless lines or take account only of the skin effects in conductors. Nowadays most of electrical and electronic systems are very integrated; so the skin and the proximity effects cannot be neglected. The analytical modeling of shielded or unshielded multiwire telecommunication and power cables proposed in this PhD report involved the calculation of cable parameters in a frequency range covering [0Hz; l0Mhz]. These calculations include the skin and the proximity effects considerations in conducting materials. In chapter 1 we point out the weakness of the existing models. A new multiwire closely line parameters is proposed in chapter II. In chapter III; a new multiwire shielded cable primary parameters is given.
