Very high and ultrahigh frequency hyperchaotic oscillators with delay line

Abstract

The paper describes the results of numerical and experimental investigations of very high and ultrahigh frequency Mackey-Glass type hyperchaos oscillators with the ring structure. The oscillators consist of a non-linear unit, a linear amplifier and a transmission line in the feedback loop. Multiple positive Lyapunov exponents confirm hyperchaotic nature of the oscillations.
