3) Consider a system on the left where the center point is origin of Cartesian coordinate system, and z = 0 is the boundary plane for material-air interface. The medium 2 is air, and medium 1 is a material with a = 10-3 s/m, ur = 2 and er = 6 Material Air The frequency is 2 GHz, and incident angle for the incident uniform plane wave is 6 degrees. The incident wave at the origin is given in the phasor domain as E, (0,0,0) = A(B, +0.5, -0.5a.) Vim Medium 1 Medium 2 where A and B are nonnegative real numbers to be calculated. The magnitude of incident wave at a point being 5 m away from the origin is 27 Find, 1) the phasor domain expressions of electric field intensities for the reflected and transmitted waves at the points each being 3 m away from the origin. i) Find the Brewser angle if any. If you find that Brewster angle does not exist, explain your reasoning
