A chain of equations describing the interaction of electromagnetic and thermal oscillations in systems with temperature-sensitive dielectrics in terms of coupled oscillators and relaxators has been obtained. The conditions of aperiodic and oscillatory instability have been determined and estimates of the threshold power of self-modulation excitation have been obtained for radio- and superhigh-frequency ferroelectric oscillatory systems and for optical-frequency microresonators such as fused quartz and water drops.
