Question
H.W1 At frequencies of 1, 100, and 3000 MHz, the dielectric constant of ice made
from pure water has values of 4.15, 3.45, and 3.20, respectively, while the loss tangent is
0.12, 0.035, and 0.0009, also respectively. If a uniform plane wave with an amplitude of
100 V/m at z 0 is propagating through such ice, find the time-average power density
at z = 0 and z 10 m for each frequency.
Ans. 27.1 and 25.7 W/m2; 24.7 and 6.31 W/m2; 23.7 and 8.63 W/m2.
