(a) Comparison of coupling coefficients for BPSWS and MPSWS; (b) electron beam profile before oscillation-starting; The voltage-dependent comparisons of (c) average output power and (d) frequency for both SWSs; The time-dependent waveforms of transient power and average power for both (e) BPSWS and (f) MPSWS, and the spectral analyses corresponding to (g) BPSWS and (h) MPSWS, respectively.
