4 shows the phase difference and magnitude ratio between [absolute value of Ex] and [absolute value of Ey].

4, the magnitude ratio ([absolute value of Ex]/[absolute value of Ey]) and phase difference (Phase(Ex)-Phase(Ey)) of the LHCP and RHCP MSDA is nearly 0 dB and [- or +]90[degrees] respectively when [f.sub.0] = 5.35 GHz, indicating the most excellent performance of circular polarization, namely the minimum AR in the boresight (along +z axis), will be obtained at this frequency.

The impedance measured by distance relay is dependent on the power system structural condition (short circuit level), angle of load and voltage magnitude ratio at the line ends (pre-fault operational condition).

The impedance measured by distance relay was formulated and it was found that it is dependent on the power system structural condition (short circuit level), angle of load and voltage magnitude ratio at the line ends (pre-fault operational condition).

Two metrics evaluated change in pressure magnitude: medial magnitude ratio and pressure sum ratio.

medial magnitude ratio = [(M).sub.test]/[(M).sub.no_mat]

When the noise-free WT peak

magnitude ratio of 60 kHz/[A.sub.0] over 522 kHz/[S.sub.0] was calculated, the ratio at 0[degrees] was 1, and at 45[degrees] it was 1.5 (see Table 4).

While the phase angle between [I.sub.INP] and [I.sub.50] is relatively small, the

magnitude ratio is significant.

The transmission coefficient is calculated from the

magnitude ratio of discrete Fourier transforms of electric fields at the output and input planes of filter.

Since the presence of noise will have the least effect on the zero-degree direction peak WT magnitudes (which were always the largest), one of the angles selected for the WT

magnitude ratio should be the zero-degree direction.

The

magnitude ratios were then collected into a set and summary statistics were calculated.
