In this work, the optical theory of physics helps to understand, analyze, and calculate the received power in a fifth-generation mobile telecommunications receiver. In these communication systems there are statistical models and deterministic physical models. We investigated how diffuse scattering in reflection contributes to specular reflection in received power at a receiver due to materials in the propagating environment in a communication channel using millimeter waves. The dimensions of building construction materials have sizes comparable to wavelength at millimeter wave frequencies. The power transmitted by communication equipment can be reflected in the roughness of these apparently smooth materials or spread out in multiple directions. The results show that the contribution due to diffuse scattering must be considered and that deterministic physical models using optical theory are valid and improve predictive analysis with good fit. With these results, the physical theory allows to make software with high precision and that improves the current applications.

Due to the strategies implemented to carry out the development of a correct teaching by virtual means, a methodological strategy of experimental tests was developed for the identification of polymeric materials through the identification of physical and chemical properties, with the objective of providing the engineering student a greater approach to the application of the scientific method and the activation of the capacity of reasoning and deductive thinking from the physical and chemical point of view. Therefore, the purpose of this research was to validate this strategy implemented with a group of engineering students, for this purpose, the strategy was implemented, and the results obtained by the students from the development of the experimentation were analyzed, the data were analyzed by means of nonparametric tests, in this case binomial test. Finally, it is concluded that the polymer identification test is feasible to be implemented as a remote laboratory, as a methodical strategy in teaching, since it allows the development of experimentation, in this case, the identification of polymeric materials, which present diverse physical properties.
