摘要：
The conditions of the formation of a spatially ordered optical structure with an ultrasound-modulated refractive index in a gradient medium have been considered. It has been shown that the excitation of a standing ultrasonic wave in the medium creates a structure consisting of trajectories of separate light beams, which is a superlattice of the "dynamic 4D photonic crystal." Regions corresponding to negative light refraction have been revealed in beam trajectories. Possible fields of application of such structures have been discussed.
