Dynamics and trajectory of nonautonomous rogue wave in a graded-index planar waveguide with oscillating refractive index
We study rogue waves in a graded-index planar waveguide with oscillating refractive index. We find that an additional refractive index can be used to manipulate the trajectory of the rogue wave without changing its shape evolution characters. The density distribution profile of rogue wave with the highest peak can be kept well through manipulating the graded-index term and nonlinear coefficient. Furthermore, the trajectories of these nonautonomous rogue waves still look like an “X” shape. These results provide possibilities to manipulate rogue wave in nonautonomous nonlinear systems.
This paper discusses some potential approaches to developing next-generation radar technologies via the development of ::: smart hardware subsystems that have the intrinsic capability to compensate for channel warping and propagation ::: distortions. Discussions with regard to typical categories of propagation distortions are provided along with a series of ::: sample scenarios that can provide challenging conditions for radar remote sensing applications. Observations of this set ::: of sample scenarios allows for the exploration of potential approaches to developing state-of-the art digital, RF, and ::: RF/Photonic technologies with intrinsic smart compensation capabilities that will enable the development of highresolution ::: radars that can operate at longer ranges while maintaining compact size and weight requirements.
