Analysis of Phase-Inversion Waves in In-and-Anti-Phase Synchronization on Coupled Van der Pol Oscillators as a 2D Lattice by Using an Actual Circuit

Abstract

In this paper, we observe phase-inversion waves which simultaneously propagate to horizontal direction and vertical direction in in-and-anti-phase synchronization by using actual circuit experiments and numerical experiments. We observe transitions of propagation velocities by changing coupling parameters between two adjacent oscillators. We clarify a reflection mechanism of the phase-inversion waves at a corner when there are in-and-anti phase synchronization for vertical direction and in-phase synchronization for horizontal direction.
