Question: A wave starts at point a, propagates 1 m through a lossy dielectric rated at 0.1 dB/cm, reflects at normal incidence at a boundary at

A wave starts at point a, propagates 1 m through a lossy dielectric rated at 0.1 dB/cm, reflects at normal incidence at a boundary at which Γ = 0.3 + j0.4, and then returns to point a. Calculate the ratio of the final power to the incident power after this round trip, and specify the overall loss in decibels.
