Electromagnetic Transmission Calculation in Single Room

The study of electromagnetic wave propagation in complex environment has always been a hot spot. In this paper, firstly, the propagation mechanism of electromagnetic wave in medium was studied. Secondly, based on Snell’s law of electromagnetic wave, the propagation path of electromagnetic wave through a single simple building was recorded, and the electric field power coverage in the shadow area of the building was obtained through the propagation path, the simulation results are analyzed.
