In this paper, a quasiparticle concept was proposed to understand the branched flow of light phenomenon. Combined with the geometrical optical theory, we successfully established a model to simulate the branched flow of light with this novel perspective. Our model owns an intuitive physics picture, without losing generality. Moreover, we demonstrated that a special structure with the fixed position and specific refractive value of quasiparticles can be designed, a controllable branched flow pattern of light will be correspondingly attained for future experimental guidance.

解释和产生分支光流的新模型

在本文中，提出了一种准粒子概念来理解光的分支流现象。结合几何光学理论，我们成功地建立了一个以这种新颖的视角模拟光的分支流的模型。我们的模型拥有直观的物理图像，并且不失一般性。此外，我们证明了可以设计一种具有固定位置和准折射比值的特殊结构，将相应地获得可控制的分支光流型，以供将来的实验指导。
