Generation of an Electrostatic Pulse and a Second Harmonic EM Pulse in a Magnetoplasma

This paper presents an investigation of the generation of an electrostatic pulse by an EM pulse (Gaussian in space and time), propagating as a right/left-handed circularly polarized mode along the static magnetic field in a collisionless magnetoplasma. The generated electrostatic pulse, again interacting with an incident EM pulse, generates a second harmonic EM pulse. The effect of self-focusing of the incident EM pulse is seen to be significant on the generated pulses.
