Dans cette thèse, nous faisons l'analyse des conditions d'existence du phénomène de supratransmission non linéaire dans deux modèles différents: un système de Klein-Gordon de cinquième ordre modifié et un système de sine-Gordon modifié. Les modèles modifiés considérés ici sont ceux avec couplage mixte, le couplage linéaire pur étant associé à un couplage non linéaire. En particulier, nous quantifions numériquement l'influence du coefficient de couplage non linéaire sur l'amplitude de seuil qui déclenche le phénomène de supratransmission non-linéaire. Notre résultat principal montre que, dans les deux modèles, lorsque le coefficient de couplage non linéaire augmente, l'amplitude de seuil déclenchant le phénomène de supratransmission non linéaire diminue. / In this thesis, we analyze the conditions of existence of the phenomenon of nonlinear supratransmission in two different models: a modified fifth-order Klein-Gordon system and a modified sine-Gordon system. The modified models considered here are those with mixed coupling, the pure linear coupling being associated with a nonlinear coupling. In particular, we quantify numerically the influence of the non-linear coupling coefficient on the threshold amplitude which triggers the phenomenon of non-linear supratransmission. Our main result shows that in both models, when the nonlinear coupling coefficient increases, the threshold amplitude triggering the phenomenon of nonlinear supratransmission decreases.
