Abstract
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.
