Summary
Synchronized oscillators are ubiquitous in nature and engineering. Synchronization is typically studied via a simplified model valid only in the weak coupling limit. Here, we report the first theoretical modeling and experimental observation of a synchronized pair of non-weakly coupled aeroelastic oscillators. We find remarkable quantitative agreement between the experiments and our theoretical higher-order phase model of non-weak coupling. Our study establishes that experimentally measured synchronization can be accurately predicted in non-weakly coupled systems and, therefore, serves as a call for a paradigm shift.
