Electromagnetic Theory Question

Please explain details, no matter late answer.

A circularly polarized uniform plane wave of phasor electric field intensity
E' = (Aâ, + j5â,- Bâ,)e J, " v/m, where A and 8 are real constants, and f =3x10° Hz
is obliquely Incident from a dielectric medium with (36,, Ho) onto another dielectric with (26,, Ho)
as shown in the figure.
o) Determine the angle of incidence 6,, so that reflected field is linearly polarized. Explain your
reasoning. You don't hove to find the numerical value of 0, you con just give sin 6, and
cos0,.
For the questions asked in parts b, c, d,and e, use the incidence ongle found in part a.
b) Find the propagatlon vectors of the incident and the reflected waves, , k,.
c) Find the numerical values of A and B.
d) Find the expression of the reflected electric field.
e) Comment on the polarization of the transmitted wave without actually computing fields.
A Find the range of incidence angles, so that incident field is totally reflected. You don't have to
find the numerical volues of 8, you can just give sin 6, ond cose.
