11. Consider a plane electromagnetic wave propagating in vacuum. The electric field is given by $\mathbf{E} = \mathbf{E}_0 e^{i(kx - \omega t)}$. The Poynting vector is labeled by $\mathbf{S}$. The intrinsic impedance $\eta$ (also called wave impedance) is $377\ \Omega$. The time-averaged Poynting vector $\langle S \rangle$ is $1\ \mathrm{W/m^2}$. Please calculate $E_0$, i.e., the amplitude of the electric field. Please choose the closest answer. (A) $54.2\ \mathrm{V/m}$ (B) $377\ \mathrm{V/m}$ (C) $19.4\ \mathrm{V/m}$ (D) $27.5\ \mathrm{V/m}$

12. Consider a plane electromagnetic wave expressed by its phasor form of $\mathbf{E} = \mathbf{E}_0 e^{i(k_x x + k_y y + k_z z)}$. The expression should satisfy the Helmholtz equation: $\nabla^2 \mathbf{E} + \omega^2 \mu \epsilon \mathbf{E} = 0$. As a result, which one of the following relations must be true? (A) $k_x + k_y + k_z = \omega \sqrt{\mu \epsilon}$ (B) $k_x^2 + k_y^2 + k_z^2 = \omega^2 \sqrt{\mu \epsilon}$ (C) $k_x^2 + k_y^2 + k_z^2 = \omega^2 \mu \epsilon$ (D) None of the above.
