As presented in the UTD Theory part, the computed electric field is the summation of elementary contributions. It is possible to select what kind of rays will be taken into account during the computation. The presented list of rays generally corresponds to the following order : from the higher energy to the lowest. However, this hierarchy may depend on the source location, on the geometry and on the observation location.

The computation time increases significantly when higher order contributions are taken into account. The computation can be 10 times longer with multiple interactions. Since these rays generally have a lower intensity, it is recommended to launch a first run with only simple contributions.

In addition, this functionality provides a good physical insight into scattering process.
