A circularly polarized uniform plane wave of phasor electric field intensity E' =(Aâ, + j\5â‚- Bâ,)e-Jk; * v/m, where A and 8 are real constants, and f= 3×10° Hz is obliquely incident from a dielectric medium with (36,, Ho) onto another dielectric with (2e,, Ho) as shown in the figure. a) Find the expression of the reflected electric field. b) Comment on the polarization of the transmitted wave without actually computing fields. c) Find the range of incidence angles, so that incident field is totally reflected. You don't have to find the numerical values of B;, you can just give sin 8; and cos 6;.
