Type-II intermittency in the driven Double Scroll Circuit

In this work, we show experimental evidences, confirmed by numerical result s, from type-Il intermittency in the driven Double Scroll Circuit. Numerica lly, we found a new scaling power law dependence on the critical parameter. This result is a consequence of the new global bifurcation scenario for th e T-2 torus breakdown observed in this system: a homoclinic saddle connecti on is the nonlinear mechanism responsible for the reinjection of the trajec tory around a repelling focus. In fact, in this global scenario the total l aminar phase is the spiraling laminar period (usually considered) plus the time the trajectory spends in the vicinity of the saddle points.
