First environment as shown in Figure 1 The air with r 1 = 1 and the second environment is r 2 = 3

First environment as shown in Figure 1 The air with ε r 1 = 1 and the second environment is ε r 2 = 3 Packed with a material. Electrical flux density in the first medium vector of D1 = 6ax – 1.5ay + 3az ( C/m^2 ) It is given as. D and E in the second environment. Determine the expressions of the vectors. Arrival and the transmission angles ( θ1 and θ2 )(There is no free load on the border.)
