tidy3d.plugins.adjoint.JaxComplexPolySlab

class JaxComplexPolySlab

Bases: JaxPolySlab, ComplexPolySlab

A ComplexPolySlab registered with jax.

Parameters:

• attrs (dict = {}) – 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, attrs are mutable. For example, the following is allowed for setting an attr obj.attrs['foo'] = bar. Also note that Tidy3D` will raise a TypeError if attrs contain objects that can not be serialized. One can check if attrs are serializable by calling obj.json().

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

• sidewall_angle (ConstrainedFloatValue = 0.0) – [units = rad]. Angle of the sidewall. sidewall_angle=0 (default) specifies a vertical wall; 0<sidewall_angle<np.pi/2 specifies a shrinking cross section along the axis direction; and -np.pi/2<sidewall_angle<0 specifies an expanding cross section along the axis direction.

• reference_plane (Literal['bottom', 'middle', 'top'] = middle) – The position of the plane where the supplied cross section are defined. The plane is perpendicular to the axis. The plane is located at the bottom, middle, or top of the geometry with respect to the axis. E.g. if axis=1, bottom refers to the negative side of the y-axis, and top refers to the positive side of the y-axis.

• slab_bounds (Tuple[float, float]) – [units = um]. Minimum and maximum positions of the slab along axis dimension.

• dilation (float = 0.0) – [units = um]. Dilation of the supplied polygon by shifting each edge along its normal outwards direction by a distance; a negative value corresponds to erosion.

• vertices (Union[ArrayLike[dtype=float, ndim=2], Box]) – [units = um]. List of (d1, d2) defining the 2 dimensional positions of the polygon face vertices at the reference_plane. The index of dimension should be in the ascending order: e.g. if the slab normal axis is axis=y, the coordinate of the vertices will be in (x, z)

• vertices_jax (Tuple[Tuple[Union[float, tidy3d.plugins.adjoint.components.types.NumpyArrayType, jax.Array, jax._src.interpreters.ad.JVPTracer, object], Union[float, tidy3d.plugins.adjoint.components.types.NumpyArrayType, jax.Array, jax._src.interpreters.ad.JVPTracer, object]], ...]) – [units = um]. Jax-traced list of (d1, d2) defining the 2 dimensional positions of the polygon face vertices at the reference_plane. The index of dimension should be in the ascending order: e.g. if the slab normal axis is axis=y, the coordinate of the vertices will be in (x, z)

• slab_bounds_jax (Tuple[Union[float, NumpyArrayType, Array, JVPTracer, object], Union[float, NumpyArrayType, Array, JVPTracer, object]]) – [units = um]. Jax-traced list of (h1, h2) defining the minimum and maximum positions of the slab along the axis dimension.

• sidewall_angle_jax (Union[float, NumpyArrayType, Array, JVPTracer, object] = 0.0) – [units = um]. Jax-traced float defining the sidewall angle of the slab along the axis dimension.
