abstract = {Circuits containing two nonlinear resonators have recently been proposed for nonreciprocal isolators, robust wireless power transfer, and sensors. A fundamental characteristic is the presence of hysteresis, associated with points of infinite slope in the solution curves. However, the prediction of hysteresis in the presence of the two distinct resonators is not possible in default harmonic balance (HB) and the additional use of continuation techniques may not be exhaustive enough. Here, we present a novel substitution method, based on the use of two auxiliary generators (AGs), that enables the system control through a single excitation voltage. A simple condition is also provided to obtain all the existing loci of infinite-slope points. The methods, which are compatible with commercial HB, will be illustrated through their application to a Lorentzian–Fano nonlinear isolator.},
