AC Conduction Assumptions

The AC conduction field solver assumes the following conditions about field quantities:

• All time-varying electromagnetic quantities have the periodic waveform:

where all quantities must have the same value of w, but can have different phase angles (q).

• If a current is not a pure sinusoid, it is decomposed into sinusoidal harmonics, and solved separately at each frequency.
• The component of E due to time-varying magnetic fields caused by conduction currents can be neglected.
