Chaotic Oscillations via Quasi-Periodicity Caused by Applying External Modulation in Ionization Waves

摘要: Dynamical behavior of nonlinear ionization waves excited in positive columns glow discharge is investigated with external modulation. It well known that competition two frequencies leads the system into a state chaotic motion via quasi-periodicity as mentioned Ruelle and Takens scenario [D. F. Takens, Commun. Math. Phys. 20, 167 (1971)]. Here, quasi-periodic route to chaos experimentally system. Quasi-periodicity realized by between self-sustained wave periodic According change rate current modulation, comes show oscillations quasi-periodicity.
