Abstract

In recent years, the theory and engineering of very high-frequency (VHF) radio-transmitting devices, as well as different devices of photonics, magnonics and plazmonics have underwent noticeable changes in connection with very rapid miniaturization and advent of new electronic components. Various VHF devices made on the basis of thin magnetic films in which magnetostatic spin waves propagate are examples of such novelties. Nonetheless, a number of fundamental physical problems still remain to be solved in the field of VHF electronics. The problem of controlling the frequency of excited oscillations by means of special mechanisms is an extremely topical issue. Nonisochronism as property of an oscillating system to change its natural frequency as a function of the external disturbance amplitude is the basic oscillation frequency control mechanism inherent in many non-linear resonators. Despite the possibility to control the frequency, which is an undoubtedly positive feature, nonisochronism also has an essential shortcoming, namely, multistability, which gives rise to saltuses between stationary oscillating modes. Therefore, the problem of compensating and controlling nonisochronism is important for nonlinear filters and self-oscillators of different physical nature. The possibility of limiting nonisochronism in an oscillating system with nonlinear damping resistance under the effect of a periodic external disturbance is investigated. Despite a wide interest in nonlinear oscillating systems, such task was not considered earlier in the theory of oscillations and its applications.
