photon transport in matlab

Photon transport in MATLAB can be done using the Monte Carlo method, which involves simulating the transport of photons in a medium by tracking their interactions with the material throughout the medium. The following steps provide an outline of how to do it:

1. Define the geometry of the medium to be simulated, including its shape and optical properties (e.g. absorption and scattering coefficients).

2. Initialize variables such as the number of photons to be simulated, the desired level of accuracy, and the location and direction of the photon sources.

3. For each photon, simulate its path through the medium by randomly selecting the distance it will travel before either being absorbed or scattering.

4. Determine the location and direction of the photon after each interaction based on the optical properties of the material.

5. Repeat steps 3 and 4 until the desired level of accuracy is achieved or until all photons have been absorbed or have left the simulated area.

6. Analyze the output data to obtain relevant information such as the spatial and directional distributions of photon absorption and scattering.
