tidy3d.Periodic#
- class Periodic[source]#
- Bases: - BoundaryEdge- Periodic boundary condition class. - Parameters:
- attrs (dict = {}) β Dictionary storing arbitrary metadata for a Tidy3D object. This dictionary can be freely used by the user for storing data without affecting the operation of Tidy3D as it is not used internally. Note that, unlike regular Tidy3D fields, - attrsare mutable. For example, the following is allowed for setting an- attr- obj.attrs['foo'] = bar. Also note that Tidy3D` will raise a- TypeErrorif- attrscontain objects that can not be serialized. One can check if- attrsare serializable by calling- obj.json().
- name (Optional[str] = None) β Optional unique name for boundary. 
 
 - Attributes - Methods - Inherited Common Usage - property bloch_vec#
- Periodic boundaries are effectively Bloch boundaries with - bloch_vec == 0. In practice, periodic boundaries do not force the use of complex fields, while Bloch boundaries do, even with- bloch_vec == 0. Thus, it is more efficient to use periodic.

- Hash method.
