Abstract
Dynamic control of chaotic dark dissipative envelope solitons in a microwave active ring resona tor containing two nonlinear elements: a one-dimensional magnonic crystal (MC) with a dynamic linear defect and a transistor amplifier is performed. Dissipative envelope solitons are formed on a long-wavelength surface magnetostatic wave propagating in the MC and parametrically decaying into short-wavelength spin waves. A constant electric current flowing through a copper conductor creates a dynamic linear defect along the longitudinal axis of the MC and controls the duty factor of the generated parametric pulses only at the MC forbidden frequency. Keywords: dissipative solitons, magnonic crystals, spin waves.
