Abstract:
A theoretical method is proposed for generating far-zone scattered fields with concentric ring-like intensity distribution by properly controlling the distribution characteristics of particles. As an example, a collection of anisotropic Gaussian-centered determinate particles with quasi-homogeneous distribution is discussed. The results show that the number and size of concentric rings can be flexibly adjusted by controlling the structural parameters of the collection of particles. In addition, by adjusting the effective length of each particle's scattering potential in different directions, a conversion of the distribution of the scattered field from the concentric ring to the crescent lobe can be achieved.
