The Periodic Condition allows modeling just one unit cell of a periodic structure, such as superlattices.

Select an option from the Type of periodicity list: Continuity (the default) or Floquet-Bloch periodicity.

For Floquet-Bloch periodicity, enter the k-vector for Floquet periodicity kF (rad/m). The default is the null vector, reducing the condition to be equivalent to Continuity. For time dependent studies, the Floquet-Bloch periodicity option does not apply. If erroneously selected, it will be reduced to the continuity condition.
