Excitation of electromagnetic waves by a current source in the inhomogeneous lossy magnetoplasma

The excitation of nonmonochromatic signals by source current and their longitudinal propagation in an inhomogeneous magnetoplasma is studied. Three types of excitation source current are considered for the study. The inhomogeneity of magneto-ionic medium is taken with respect to the variation in plasma density and strength of the magnetic field. The effect of interparticle collisions on the amplitude of the signal is studied. Properties of the excited signals are discussed in different frequency ranges in terms of charge per unit length of the excitation source and the distance of propagation of the signal.
