Abstract content <br> &nbsp; (Max 300 words)

Nonlinearly coupled dust-acoustic and dust-cyclotron electric field waveforms are investigated for a three-component dusty plasma composed of streaming adiabatic negative dust drifting parallel to the ambient magnetic field, Boltzmann electrons and Boltzmann ions. The Fast Fourier Transform (FFT) algorithm will be applied to the sinusoidal, sawtooth and spiky electric field waveforms to identify the dominant frequency components of the nonlinear structures. The possibility of obtaining oscilloton structures will be investigated by including charge separation effects.
