We propose a novel forcing technique of spatially extended self-oscillatory systems able to excite phase bistability and the dissipative structures associated with it. The forcing is time periodic at a frequency close to the oscillators' frequency and is spatially modulated. The effects of this type of forcing are demonstrated analytically and numerically in a directly driven complex Ginzburg-Landau equation. Both spatially periodic and spatially random drives prove to be effective.
我们提出了一种新的空间扩展自激系统的强制技术,能够激发与之相关的相双稳和耗散结构。这种强制力是时间周期性的,频率接近振荡器的频率,并且是空间调制的。在直接驱动的复金兹堡-朗道方程中,对这种强制力的影响进行了分析和数值验证。空间周期性和空间随机驱动都被证明是有效的。
