- Abstract
- A multiple reflection model inside a self-evolving cavity was developed based on the level set method. The ray tracing technique was adopted, considering the specular mode of reflection. Simulation was carried out for five different surfaces: two fake drill hole surfaces, one fake keyhole surface, one self-consistent drill hole surface, and one self-consistent keyhole surface. The study revealed many interesting findings regarding multiple reflections.
