On the feasibility of a parametric generator of hyperbolic chaos

A chaos generator consisting of two subsystems is considered. Each subsystem is a pair of parametrically coupled oscillators whose free-running frequencies differ by a factor of two. The subsystems are alternately driven by the third harmonic of a basic frequency, and energy is transferred between them through signal squarers. Based on a qualitative analysis and numerical results, a hypothesis is put forward that the system implements a hyperbolic strange attractor
