of a plane electromagnetic wave propagating in free space: \mathbf{H}=\hat{\mathbf{x}} H_{0} e^{j \beta y}+\hat{\mathbf{z}} H_{1} e^{j \beta y} \quad[\mathrm{~A} / \mathrm{m}] (a) Calculate the electric field intensity using the properties of the Poynting vector. (b) Show that the result in (a) is correct by substituting the magnetic field intensity into Maxwell's equations and evaluating the electric field intensity through Maxwell’s equations.
