From what I understand from the raypl function of the ray tracing model in matlab ( https://www.mathworks.com/help/antenna/ref/raypl.html ) it is doable to edit the "type" of reflection by the specification of the material on any ray interaction. I'd like to ask whether it is also doable to do the same thing by including the diffractions( the function says no ). Is there any other function to include such configuration about diffraction losses.

My main goal is to acquire a ray which will have a customized propagation loss ( free space losses, different material reflection loss, diffraction losses).

Hi Stavros,

Using the function ‘raytrace’ you can edit the type of reflection by selecting surface material, using the "SurfaceMaterial" parameter, and you can select the maximum number of diffractions, reflections, etc. Use this example to get a better idea on how to use this function.

Thanks for the answer, but from what I understand choosing a surface material considers every object on the map being of that material. Is it possible to have multiple material objects on a cartesian map on the ray tracer ?
