Figure 5: fft spectrum for mse operating with both pems at their customary retardance<br />
(R 1 = R 2 = π) for imperfect perfect mirrors having a moderate phase shift, δ = 5 o and<br />
unity reflectivity for S- and P- polarization. A field-line pitch angle <strong>of</strong> 24 o with respect to<br />
the pem optics is assumed. Note that the mirror’s phase shift creates new but rather small<br />
fft amplitudes near the first and third harmonics <strong>of</strong> both pem frequencies. This is the same<br />
case as the previous plot, Fig. 4, but plotted on a log scale to allow the identification <strong>of</strong><br />
low-amplitude components.<br />
