tidy3d.components.geometry.Planar

class tidy3d.components.geometry.Planar

Geometry with one axis that is slab-like with thickness height.

Parameters

• center (Tuple[float, float, float] = (0.0, 0.0, 0.0)) – [units = um]. Center of object in x, y, and z.

• axis (Literal[0, 1, 2] = 2) – Specifies dimension of the planar axis (0,1,2) -> (x,y,z).

• length (Optional[NonNegativeFloat] = None) – [units = um]. Defines thickness of geometry along axis dimension.

Fields

• axis (Literal[0, 1, 2])

• length (pydantic.types.NonNegativeFloat)

attribute axis: Literal[0, 1, 2] = 2

Specifies dimension of the planar axis (0,1,2) -> (x,y,z).

attribute length: pydantic.types.NonNegativeFloat = None

Defines thickness of geometry along axis dimension.

Constraints

• minimum = 0

intersections(x: Optional[float] = None, y: Optional[float] = None, z: Optional[float] = None)

Returns shapely geometry at plane specified by one non None value of x,y,z.

Parameters

• x (float) – Position of plane in x direction, only one of x,y,z can be specified to define plane.

• y (float) – Position of plane in y direction, only one of x,y,z can be specified to define plane.

• z (float) – Position of plane in z direction, only one of x,y,z can be specified to define plane.

Returns

• List[shapely.geometry.base.BaseGeometry] – List of 2D shapes that intersect plane. For more details refer to

• `Shapely’s Documentaton <https (//shapely.readthedocs.io/en/stable/project.html>`_.)

property bounds

Returns bounding box for planar geometry, may implement for subclasses.

Returns

Min and max bounds packaged as (minx, miny, minz), (maxx, maxy, maxz).

Return type

Tuple[float, float, float], Tuple[float, float float]
