Chapter 5, Problem 5.46P

A wave specified by ${\text{E}}^{\text{i}}=100.\cos \left(\pi \times {10}^{7}t-{\beta }_{1}z\right){\text{a}}_x\text{V/m}$ is incident from air (at $z<0$ ) to a nonmagnetic media $\left(z>0,\sigma =0.050{\text{S/m,ε}}_{\text{r}}=9.0\right)$. Find ${\text{E}}^{\text{r}},{\text{E}}^{\text{t}}$, and SWR. Also find the time-averaged power densities for the incident, reflected and transmitted waves.
