A uniform plane wave in region 1 is normally incident on the planar boundary separating regions 1
Question:
A uniform plane wave in region 1 is normally incident on the planar boundary separating regions 1 and 2. If ∈"1 = ∈"2 = 0, while ∈'r1 = μ3r1 and ∈'r2 = μ3r2, find the ratio ∈'r2/∈'r1 if 20% of the energy in the incident wave is reflected at the boundary. There are two possible answers.
