Boundary Conditions

tidy3d.BoundarySpec	Specifies boundary conditions on each side of the domain and along each dimension.
tidy3d.Boundary	Boundary conditions at the minus and plus extents along a dimension.
tidy3d.BoundaryEdge	Electromagnetic boundary condition at a domain edge.

Types of Boundaries

tidy3d.Periodic	Periodic boundary condition class.
tidy3d.PECBoundary	Perfect electric conductor boundary condition class.
tidy3d.PMCBoundary	Perfect magnetic conductor boundary condition class.
tidy3d.BlochBoundary	Specifies a Bloch boundary condition along a single dimension.

Absorbing Boundaries

Types of Absorbers

tidy3d.PML	Specifies a standard PML along a single dimension.
tidy3d.StablePML	Specifies a 'stable' PML along a single dimension.
tidy3d.Absorber	Specifies an adiabatic absorber along a single dimension.

Absorber Parameters

tidy3d.AbsorberParams	Specifies parameters common to Absorbers and PMLs.
tidy3d.PMLParams	Specifies full set of parameters needed for complex, frequency-shifted PML.
