Abstract
When the metal wire is irradiated with a beam of laser, a light ring will appear on the screen. The formation mechanism of the light ring is discussed in this article. It is also discussed how various parameters, including the shape of the laser beam, the laser diameter, the wire diameter, the wire roughness, and the incidence angle, influence the ring through computational simulation and experiments simultaneously. Our calculation is in good agreement with experimental results.
