flex_rf.tidy3d.InternalAbsorber
Type: class │ Base(s): Box
Description
Section titled “Description”Internally placed plane with one-way wave equation boundary conditions for absorption of electromagnetic waves. Note that internal absorbers are automatically wrapped in a PEC frame with a backing PEC plate on the non-absorbing side.
Parameters
Section titled “Parameters”size [TracedSize] |
|
Size in x, y, and z directions. |
center [TracedCoordinate] = (0.0, 0.0, 0.0) |
|
Center of object in x, y, and z. |
direction [Direction] = ... |
|
Indicates which direction of traveling waves are absorbed. |
grid_shift [int] = 0 |
|
Displacement of absorber in the normal positive direction in number of cells. This could be used to conveniently place an absorber right behind a source: one can use the same |
boundary_spec [ModeABCBoundary | ABCBoundary] = ... |
|
Boundary specification for defining effective propagation index in the one-way wave equation. |
Methods
Section titled “Methods”plot(x: float | None = None, y: float | None = None, z: float | None = None, ax: Ax | None = None, **patch_kwargs: Any) |
|
Plot this absorber. |
plot_params() |
|
Default parameters for plotting a port absorber object. |
