Number: Signature: 4. (25 points) The electric field intensity of a plane wave propagating in wood (e,= 16, H=1) is given as E(r)=3(-2) e-j2x(y+z) This plane wave is incident on a medium with &, 4 and 4, 16 which occupies the half space z > 0. a) (3 points) What is the direction of propagation? b) (2 points) What is the angle of incidence ;? c) (2 points) Is this wave TEz (L) or TMZ (//) polarized? = d) (5 points) What is the angle of reflection 6, and the angle of refraction 6,? e) (8 points) Find the reflection and transmission coefficients. f) (5 points) Find the electric field intensity of the reflected wave.
