Ponderomotive force driven mechanism for electrostatic wave excitation and energy absorption of electromagnetic waves in overdense magnetized plasma

The excitation of electrostatic waves in plasma by laser electromagnetic (EM) pulse is important as it provides a scheme which the power from EM field can be transferred into medium. paper presents fundamentally new ponderomotive pressure-driven mechanism an overdense magnetized finite pulse. Particle-in-cell simulations using EPOCH-4.17.10 framework have been utilized for study interacting with external magnetic chosen to aligned parallel propagation direction. In this geometry, wave inside identified whistler or R and L waves. group velocity these being different, clear spatial separation pulses are visible. addition, perturbation associated propagating also observed. These perturbations they couple energy oscillations understood here charge created difference between force (of pulse) felt two species, viz., electrons ions plasma.
