Question: A 10 MHz uniform plane wave having an initial average power density of 5 W/m 2 is normally incident from free space onto the surface

A 10 MHz uniform plane wave having an initial average power density of 5 W/m² is normally incident from free space onto the surface of a lossy material in which ∈"₂/∈'₂ = 0.05, ∈'_r2 = 5, and μ₂ = μ₀. Calculate the distance into the lossy medium at which the transmitted wave power density is down by 10 dB from the initial 5 W/m².
