2.5D relativistic electromagnetic PIC code for simulation of beam interaction with plasma in axial-symmetric geometry was developed. Accurate charge weighting scheme and difference schemes near the system axis were introduced. ...

Dynamics of electron bunch in homogeneous plasma was studied via electromagnetic PIC method in the cylindrical geometry using PIC method. Electrostatic wake wave propagated behind the bunch in plasma as predicted by the ...

Regions of the most effective transformation of current wave into electromagnetic wave for the charged particle moving along the density gradient in magnetic field, which is parallel to the plasma density gradient, are ...
