Figure 21: fft spectrum for mse operating with both pems with the second pem operating<br />
at a standard retardance (R 2 = π) but the first pem operating at a retardance that sits at<br />
the zero <strong>of</strong> the zero-th order Bessel function, R 1 = 2.405 for an imperfect mirror having a<br />
large phase shift, δ = 30 o . A field-line pitch angle <strong>of</strong> 24 o with respect to the pem optics<br />
is assumed. As predicted by the <strong>MSE</strong> Memo #7, the choice <strong>of</strong> this retardance for pem#1<br />
removes the fft amplitude at ω 2 .<br />
