Photon transport refers to the movement of photons, which are particles of light, through various media. This process is essential in fields like optics and telecommunications, where understanding how light travels can improve technologies such as fiber optics and imaging systems. The behavior of photons can be influenced by factors like scattering, absorption, and reflection, depending on the material they encounter. In many applications, such as solar energy and medical imaging, efficient photon transport is crucial for maximizing performance. Researchers study the principles of quantum mechanics and electromagnetic theory to develop better methods for controlling and utilizing light, leading to advancements in both science and technology.
