First, since \(\eta_c\) is the ratio of the magnitude of the electric field intensity to the magnitude of the magnetic field intensity, the phase of the magnetic field will be shifted by \(\approx\pi/...First, since \(\eta_c\) is the ratio of the magnitude of the electric field intensity to the magnitude of the magnetic field intensity, the phase of the magnetic field will be shifted by \(\approx\pi/4\) relative to the phase of the electric field in a good conductor. The easiest way to derive this result is to work in polar form, in which \(-j\) is 1 at an angle of \(-\pi/2\), and the square root operation consists of taking the square root of the magnitude and dividing the phase by 2.↩
