An RCP wave in free space with Eˢᵢ=(aₓ - jaᵧ)e⁻ʲᵏ⁰ᶻ is normally incident upon a semi-infinite lossless medium with εᵣ and μᵣ. The reflected and transmitted field phasors are given by Eˢᵣ = (Tₓaₓ - jTᵧaᵧ) eʲᵏ⁰ᶜ² and Eˢᵣ = (Tₓaₓ - jTᵧaᵧ) e⁻ʲᵏᶻ. Given that the boundary is z=0 , obtain Tₓ, Tᵧ, Tₓ, and Tᵧ.
