Moist soil has a conductivity of $\sigma = 10^{-3}$ S/m and $\epsilon_r = 2.5$. Find conduction current $J_c$. Given, $E = 6 \times 10^{-6} \sin 9 \times 10^{3} t$ V/m.

A wave is incident at an angle of 30°, from air to Teflon. Find the angle of transmission. Given, \(\epsilon_r\) = 2.1, \(\mu_1 = \mu_2\)

Calculate the propagation constant \( \gamma \) for a conducting medium in which \(\sigma\) = 58 MS/m, \( \mu_r \) = 1 and f = 100 MHz.
