Detailed analysis of MSE spectra

Figure 2: Computed fft spectrum for mse operating with both pems at their customary
retardance (R 1 = R 2 = π) for perfect mirrors having no shift, δ = 0 o and equal reflectivity
for S- and P- polarization. A field-line pitch angle of 24 o with respect to the pem
optics is assumed. Magenta vertical lines indicate the frequencies corresponding to simple
harmonics of the pem frequencies. The blue lines represent the fft amplitudes that are
close to frequencies expected for ideal mirrors listed in Table 1. In subsequent plots, green
lines represent fft amplitudes that are near frequencies expected from the non-ideal mirror
characteristics.
