论文摘要
不均匀材料的反向散落问题已经引起了很多年的关注，并且通常通过各种优化技术解决。在本文中，我们提出了一种无优化的方法，用于解决一维不均匀介质的反散射问题，并使用它来证明所需反射频率响应的设计。此外，我们得出了模拟问题的管理方程 - 一种与时间相关的均匀介质，并使用相同的技术设计时间切换曲线，以设计k空间中的频率响应。
The inverse-scattering problem of an inhomogeneous material has been of interest for many years, and was generally addressed with various optimization techniques. In this paper, we suggest an optimization-free method for solving the inverse-scattering problem of a one-dimensional inhomogeneous medium and use this to demonstrate the design of desired reflection frequency response. In addition, we derive the governing equation of an analog problem - a time-dependent homogeneous medium and use the same technique to design a temporal switching profile for the design of frequency response in k-space.
