An aluminum waveguide with $a=4.2 \mathrm{~cm}, b=1.5 \mathrm{~cm}, \sigma_c=3.5 \times 10^7 \mathrm{mhos} / \mathrm{m}$, filled with telfon $\left(\mu_r=1, \epsilon_r=2.6, \sigma=10^{-15} \mathrm{mhos} / \mathrm{m}\right)$ operates at $4 \mathrm{G} \mathrm{Hz}$. Determine,
(a) $\alpha_c$ and $\alpha_d$ for $T E_{10}$ mode
(b) The waveguide loss in dB over a distance of $1.5 \mathrm{~m}$.
