Subpixel Averaging

Subpixel Averaging#

tidy3d.SubpixelSpec

Defines specification for subpixel averaging schemes when added to Simulation.subpixel.

Types of Subpixel Averaging Methods#

tidy3d.Staircasing

Apply staircasing scheme to material assignment of Yee grids on structure boundaries.

tidy3d.VolumetricAveraging

Apply volumetric averaging scheme to material properties of Yee grids on structure boundaries.

tidy3d.HeuristicPECStaircasing

Apply a variant of staircasing scheme to PEC boundaries: the electric field grid is set to PEC if the field is substantially parallel to the interface.

tidy3d.PolarizedAveraging

Apply a polarized subpixel averaging method to dielectric boundaries.

tidy3d.PECConformal

Apply a subpixel averaging method known as conformal mesh scheme to PEC boundaries.

tidy3d.SurfaceImpedance

Apply 1st order (Leontovich) surface impedance boundary condition to structure made of LossyMetalMedium.
