Computation of Reflection Loss

Similar to the reflection, described in the previous subsection, an individual transmission/ penetration loss can be defined (in dB) for each element. If a ray is reflected at the object, this loss is added to the propagation loss of the ray. WinProp offers a table (MS EXCEL sheet) with different materials and their specific reflection losses. So, you can enter the material, and the sheet provides the appropriate reflection loss to be used.

Reflections at dielectric surfaces do lead to a phase shift of 180°. Therefore, an additional phase offset of 180° is added to the phase of the ray at the receiver and considered during the superposition.

The angle dependency of the reflection loss is not considered in MASC as its influence is not so high concerning the accuracy of the modeling of the scenario.
