Particle simulation code for charge variable dusty plasmas
Bizhan Farokhi
Charges on the dust grains immersed in a plasma vary in time. We follow the hydrodynamic approach to obtain dispersion relations for some low frequency electrostatic modes, taking…

Chaotic particle dynamics in free-electron lasers with coaxial wiggler
B. Farokhi, S. Mobarakabadi
The motion of a relativistic test electron in a free electron laser can be altered significantly by an ideal coaxial wiggler field and uniform axial guide field. I have investigate…
