Profile of the quasi-parallel DL with its corresponding electric pulse and the FFT power spectra. (a) DL electrostatic potential expressed in volts (V) in dependence on the spatial width in m. (b) Associated electric pulse for different values of the magnetic field. (c) Corresponding FFT spectra of the electric waveforms, where the x-axis represents log₁₀v, where v is the frequency in Hz, and the y-axis signifies the power of the electric pulse, expressed in decibels dB.
