Analysis of the breakdown of complete synchronization in two identical capacitively coupled van der Pol oscillators each containing a diode

Key Points

• Complete synchronization degradation occurs when the coupling strength varies, highlighting the role of phase shifts.
• In simulations, varying diode characteristics led to distinct oscillation phases, revealing critical influences on synchronization stability.
• Observational analysis of coupled behaviors shows how changes among oscillators can disrupt their synchronized states over time.
• Results imply the practical importance of understanding synchronization for developing more reliable electronic circuits, especially in communication systems.
