Description

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:

  1. All the materials can be assumed to be linear (ie. permittivity constant)
  2. 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)
  3. 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.
