Chirality detected in Hartley’s electronic oscillator

Abstract Chirality is an elusive asymmetry important in science and technology confined mainly to the quantum realm. This paper reports observation of chirality a classical (that is, not quantum) scenario, namely stability diagrams autonomous electronic oscillator with junction-gate field-effect transistor (JFET) tapped coil. As number spikes (local maxima) stable oscillations changes along closed parameter paths, they generate two types intricate structures. Surprisingly, such pair structures are artful images each other when reflected on mirror. They dual chiral pairs interconnecting families loops. Chiral should be difficult detect experimentally. conjectured generic property nonlinear oscillators governed by equations.
