1-a)In an atmospheric environment, two very wide dielectric planar layers with a thickness of 15 cm (Er1 = 5) and 25 cm (Er2 = 10) are separated by an air layer 10 cm thick. An electric field of 10 V / m amplitude is applied to the thin layer at an angle of pi / 3 rad. Accordingly a) Find the angle and amplitude of the exit from the thick layer. b) Calculate the values of E, D and P vectors for each environment
