tidy3d.PlaneWave#

class PlaneWave[source]#

Uniform current distribution on an infinite extent plane. One element of size must be zero.

Parameters:

name (Optional[str] = None) – Optional name for the source.
center (Tuple[float, float, float] = (0.0, 0.0, 0.0)) – [units = um]. Center of object in x, y, and z.
size (Tuple[NonNegativeFloat, NonNegativeFloat, NonNegativeFloat]) – [units = um]. Size in x, y, and z directions.
source_time (Union[GaussianPulse, ContinuousWave, CustomSourceTime]) – Specification of the source time-dependence.
direction (Literal['+', '-']) – Specifies propagation in the positive or negative direction of the injection axis.
angle_theta (float = 0.0) – [units = rad]. Polar angle of the propagation axis from the injection axis.
angle_phi (float = 0.0) – [units = rad]. Azimuth angle of the propagation axis in the plane orthogonal to the injection axis.
pol_angle (float = 0) – [units = rad]. 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.

Example

>>> pulse = GaussianPulse(freq0=200e12, fwidth=20e12)
>>> pw_source = PlaneWave(size=(inf,0,inf), source_time=pulse, pol_angle=0.1, direction='+')
