Solved Problems-12

A uniform plane wave of frequency ‘f ’ is normally incident from air onto a thick conducting sheet with conductivity σ and ε = ε0, μ = μ0. Show that the proportion of power transmitted into the conductor (and then dissipated into heat) is given approximately by,
Description: 41143.png, Rs = Surface resistance

Calculate this quantity for f = 1 GHz and copper, σ = 5.8 ∞ 107 siemens/m.
For a good conductor, Description: 41135.png
So, Description: 41125.png
So, the complex characteristic impedance for a good conductor is,
or, Description: 41118.png

∴ transmission coefficient,
Description: 41111.png
∴ reflection coefficient,
Description: 41101.png
So, the power transmission coefficient is,
