Diffracted Rays

The explanations for the reflected rays with the size of the objects and their distance to the radiator is even more important for the diffractions. And the diffraction losses are high – compared to the reflection losses.

So MASC does not consider any diffractions in the computation of the resulting patterns. Diffractions would only be interesting if no reflecting or transmitting ray would reach the point currently examined. But this can never be the case as an unlimited number of transmissions / penetrations are supported, and therefore at least the direct ray is examined for each point examined.
