Afterwards, Stathopoulos and Zhou [4] presented the paper which shows the numerical prediction of turbulent wind pressures on the building surfaces with sharp corners of right angles for different wind incidence angle. Miyashita et al.
The usual method to solve Maxwell's equations has been carried out in detail for a hybrid cell similar to the one considered here [37], and it is found that there is a regime for the incidence angle i where the ray trajectory presents a caustic, that is, a geometrical place where the beam bends and remains inside the cell until it returns back towards the incidence substrate (see Figure 1).
