The flight of charged particles in a time varying electric field can be modelled as a linear superposition of scaled electrostatic fields from voltage driven electrodes. Providing that:

- All the materials can be assumed to be linear (ie. permittivity constant)
- Frequency of the time variation of the fields is such that the wavelength associated with the fields is large compared to the length of the system (at least 20 times)
- Eddy currents or diffusion of the fields can be neglected (ie. there are no dielectrics with small, but finite, conductivity in the system)

The OPERA-3d analysis program TOSCA can be used for this type of electrostatic simulation.

*If the wavelength of the associated fields was of a comparable dimension to the system length it would be necessary to use a SOPRANO high frequency simulation.*

*If there were finite conductivity dielectrics in the device it might be necessary to use an ELEKTRA quasi static simulation.*
