Chapter 12: Problem 2
The plane \(z=0\) defines the boundary between two dielectrics. For \(z<0\), \(\epsilon_{r 1}=9, \epsilon_{r 1}^{\prime \prime}=0\), and \(\mu_{1}=\mu_{0} .\) For \(z>0, \epsilon_{r 2}^{\prime}=3, \epsilon_{r 2}^{\prime \prime}=0\), and \(\mu_{2}=\mu_{0}\) Let \(E_{x 1}^{+}=10 \cos (\omega t-15 z) \mathrm{V} / \mathrm{m}\) and find \((a) \omega ;(b)\left\langle\mathbf{S}_{1}^{+}\right\rangle ;(c)\left\langle\mathbf{S}_{1}^{-}\right\rangle\); (d) \(\left\langle\mathbf{S}_{2}^{+}\right\rangle\).
