A uniform plane electromagnetic wave incident normally on a plane surface of a dielectric material is reflected with a VSWR of 3. What is the percentage of incident power that is reflected (a) 10% (b) 25% (c) 50% (d) 75% |

Answer» (b) 25% VSWR = \(\frac{1+|r|}{1-|r|}\) 3 = \(\frac{1+|r|}{1-|r|}\) r = 0.5 \(\frac{p_r}{p_i}\) = r2 = (0.5)2 = 0.25 25% of incident power is reflected. |
