Parts D-F

The electric field of a plane wave propagating in a nonmagnetic material is given by:

\[
E = \begin{bmatrix} 
0 \\ 
3 \cdot \cos(2 \cdot \pi \cdot 10^7 \cdot t - 0.4 \cdot \pi \cdot x) \\ 
4 \cdot \cos(2 \cdot \pi \cdot 10^7 \cdot t - 0.4 \cdot \pi \cdot x) 
\end{bmatrix} \cdot \frac{V}{m}
\]

Find the following:
(a) The direction of wave propagation.  
(b) The phase velocity.  
(c) The relative permittivity of the material.  
(d) The intrinsic impedance.  
(e) The magnetic field phasor \(\mathbf{H(z)}\).  
(f) The instantaneous magnetic field \(\mathbf{H(z,t)}\).
