tidy3d.components.source.AngledFieldSource

class AngledFieldSource

Bases: DirectionalSource, ABC

A FieldSource defined with an angled direction of propagation.

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.

• direction (Attribute: direction) –

  Type	Literal[‘+’, ‘-‘]
  Default
  Description	Specifies propagation in the positive or negative direction of the injection axis.

• angle_theta (Attribute: angle_theta) –

  Type	float
  Default	= 0.0
  Units	rad
  Description	Polar angle of the propagation axis from the injection axis.

• angle_phi (Attribute: angle_phi) –

  Type	float
  Default	= 0.0
  Units	rad
  Description	Azimuth angle of the propagation axis in the plane orthogonal to the injection axis.

• pol_angle (Attribute: pol_angle) –

  Type	float
  Default	= 0
  Units	rad
  Description	Specifies the angle between the electric field polarization of the source and the plane defined by the injection axis and the propagation axis (rad). pol_angle=0 (default) specifies P polarization, while pol_angle=np.pi/2 specifies S polarization. At normal incidence when S and P are undefined, pol_angle=0 defines: - Ey polarization for propagation along x.- Ex polarization for propagation along y.- Ex polarization for propagation along z.

Notes

The direction is defined by the polar and azimuth angles w.r.t. an injection axis, as well as forward + or backward -. This base class only defines the direction and injection_axis attributes, but it must be composed with a class that also defines angle_theta and angle_phi.
