Fresnel equations in the case where the incident wave (that is, the electric fields of the waves

) .Is parallel to the plane of incidence (it is the plane where the three wave vectors co-exist). Analyze the case where the incident wave is perpendicular to the plane of incidence. Impose boundary conditions: a)Get the Fresnel equations to

? ?and

b)graph

? ?and

? ?as a function of ?i dor the case ? = 1.5.

c)Is there a Brewster angle in the general case (any value of ?)?. Demonstrate and explain.

d)check that the Fresnel equations are reduced to the known way to normal incidence.
