两个阻尼耦合振子已被用来证明例外点的发生在一个纯粹的经典系统。该实施方案是用kHz范围内的电子电路实现的。实验结果与数学预测在例外点处完全吻合。本文最后讨论了例外点的普遍存在性--将耗散与空间方向联系起来。
Two damped coupled oscillators have been used to demonstrate the occurrence of exceptional points in a purely classical system. The implementation was achieved with electronic circuits in the kHz-range. The experimental results perfectly match the mathematical predictions at the exceptional point. A discussion about the universal occurrence of exceptional points—connecting dissipation with spatial orientation—concludes this paper.
