The plane wave ???? = ???????? ???????????? (???????? − ????????)???????? ????/???? in a lossless medium (μ = 4μ0,  = 0) encounters a lossy medium (μ = μ0 ,  = 40, σ = 0.1 S/m) normal to the x-axis at x=0. Find (a) Γ, τ, and SWR (b) Er and Hr (c) Et and Ht (d) The time average Poynting vectors in both regions
