The values of modulation coefficient m f are set as 0.1, 0.5, 1, 4, and 10, respectively.
Furthermore, to show the effect of modulation coefficient m f to the matching component function, different modulation coefficients are used to estimate the NZ index.
In-plane wave and flexural shear wave dispersions are obtained for a range of values of a stiffness modulation coefficient.
Future work may focus on the adaptive adjustment algorithm of the amplitude modulation coefficient in the SCCS model.
Figure 9 presents the correct ratio of NZ index using different modulation coefficient.
SFM signal is adopted as the LOS modulation for the NYFR, and the LOS modulation can be expressed as m(t) = 2πf s t + m f sin(2πf sin t) + φ LOS, where the LOS carrier frequency f s is 1 GHz, the LOS modulation coefficient m f is 4, the LOS modulation frequency f sin is 10 MHz, the LOS initial phase φ LOS is 0, and the number of the monitored Nyquist zones is 10.
The power spectrum of the light intensity examined by the FMLSI technique is given by [ 31] P (f ) = ∫ S [ t, f − (t + t 0 ) β ] ρ (t ) d t. (2)Here, β = Δ ν f m is the optical frequency modulation coefficient, Δ ν is the modulation range, f m is the modulation frequency, t 0 takes account of the time difference for light traveling in the two arms of the interferometer.
For regenerative NeMo, we do not need to provide the information of modulation coefficients, since the coefficients are uniquely determined by the degree of the packet.

In this paper, we will examine in more detail the first of these possibilities: the modulation of the reflection coefficient of electromagnetic VLF waves from the ionosphere (cf. Bespalov et al., 2003).
