tidy3d.rf.CompositeCurrentIntegral

class CompositeCurrentIntegral

Bases: CompositeCurrentIntegralSpec

Current integral comprising one or more disjoint paths

Parameters:

• path_specs (tuple[Union[AxisAlignedCurrentIntegralSpec, Custom2DCurrentIntegralSpec, AxisAlignedCurrentIntegral, Custom2DCurrentIntegral], …]) – Disjoint path specifications – or already-built path integrals – for each isolated contour integral.

• sum_spec (Literal['sum', 'split']) – Determines the method used to combine the currents calculated by the different current integrals defined by path_specs. sum simply adds all currents, while split keeps contributions with opposite phase separate, which allows for isolating the current flowing in opposite directions. In split version, the current returned is the maximum of the two contributions.

Example

>>> spec1 = AxisAlignedCurrentIntegralSpec(center=(0, 0, 0), size=(1, 1, 0), sign="+")
>>> spec2 = AxisAlignedCurrentIntegralSpec(center=(2, 0, 0), size=(1, 1, 0), sign="+")
>>> composite = CompositeCurrentIntegral(path_specs=(spec1, spec2), sum_spec="sum")
