3D AC Conduction
AC conduction analysis is the study of
- electric field
- current
- losses
- lumped parameters (CG)
The AC conduction field solver allows you to analyze both conduction and displacement currents due to time-varying electric fields in conductors and perfect and lossy dielectrics.
Use it to analyze current distributions, electric field distributions and potential differences, and CG parameters. For instance, the admittance matrix associated with a structure can be computed using the AC conduction field solver. In addition, any quantity that can be derived from the basic electrical quantities (Electric Field, current densities, etc.) can then be analyzed.
The AC conduction field solver assumes that all sources are sinusoids oscillating at the same frequency. Optionally, you may specify different phase angles for different sources.
You need to specify these related material properties: permittivity, conductivity (for lossy materials), frequency-dependent dielectric loss tangent. You also must specify the current, electric potential at one or more object interfaces or boundaries in the model. The AC conduction field solver then computes the electric potential for the model. From the electric potential, it derives the electric field, E, the electric flux density, D, and the current density, J.
The supported 3D material models can be found in the table in Maxwell Solvers Material Properties.
