Detailed Description

This is the implementation file for the particleswarm electromagnetic source, used for the self-consistent finite element time domain maxwell solver that models propagation of charged particles through accelerators.

Copyright by Benedikt Oswald, 2002-2007, all rights reserved.

Objective: implements class and its methods of a class, i.e. numproc in UG speak, for providing an electromagnetic current density source, based on the concept of charged particles that propagate through accelerator structures. The particles' location, velocity and momentum is used for computing equivalen electric current densities which are then fed into the right hand side of the curl-curl equaiton for the electric field.

Attention:

none required

Bug:

this is a research code.

Todo:

it would be useful to import precomputed cavity fields.
