At frequencies of 1 MHz, the dielectric constant of ice made from pure water has values of 4.15, respectively, while the loss tangent is 0.12, also respectively. If a uniform plane wave with an amplitude of 100 V/m at z = 0 is W/m^2 and z = 10 propagating through such ice, find the time-average power density at z = 0 m W/m^2.
