Observation of exceptional points in electronic circuits

Stehmann T. ; Heiss W.D. ; Scholtz F.G. (2004)


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.
