# Frequency

## Reminder

The Steady State AC Electric application can be used to deal with low frequency problems.

At low frequency, the equations of the electric fields and and the equations of the magnetic field and can be decoupled.

This separation depends on: materials, work frequencies, size of the study domain. This separation is usually regarded as valid for frequencies in the range f < 1 to 10 GHz.

The frequency is defined during the choice of the application.
