tidy3d.components.source.BroadbandSource

class BroadbandSource

Bases: Source, ABC

A source with frequency dependent field distributions.

Parameters:

• name (Attribute: name) –

  Type	Optional[str]
  Default	= None
  Description	Optional name for the source.

• center (Attribute: center) –

  Type	Tuple[float, float, float]
  Default	= (0.0, 0.0, 0.0)
  Units	um
  Description	Center of object in x, y, and z.

• size (Attribute: size) –

  Type	Tuple[NonNegativeFloat, NonNegativeFloat, NonNegativeFloat]
  Default
  Units	um
  Description	Size in x, y, and z directions.

• source_time (Attribute: source_time) –

  Type	Union[GaussianPulse, ContinuousWave, CustomSourceTime]
  Default
  Description	Specification of the source time-dependence.

• num_freqs (Attribute: num_freqs) –

  Type	ConstrainedIntValue
  Default	= 1
  Description	Number of points used to approximate the frequency dependence of injected field. A Chebyshev interpolation is used, thus, only a small number of points, i.e., less than 20, is typically sufficient to obtain converged results.
