tidy3d.PlaneWave#
- class PlaneWave[source]#
Bases:
AngledFieldSource
,PlanarSource
Uniform current distribution on an infinite extent plane. One element of size must be zero.
- Parameters:
attrs (dict = {}) β Dictionary storing arbitrary metadata for a Tidy3D object. This dictionary can be freely used by the user for storing data without affecting the operation of Tidy3D as it is not used internally. Note that, unlike regular Tidy3D fields,
attrs
are mutable. For example, the following is allowed for setting anattr
obj.attrs['foo'] = bar
. Also note that Tidy3D` will raise aTypeError
ifattrs
contain objects that can not be serialized. One can check ifattrs
are serializable by callingobj.json()
.name (Optional[str] = None) β Optional name for the source.
center (Tuple[float, float, float] = (0.0, 0.0, 0.0)) β [units = um]. Center of object in x, y, and z.
size (Tuple[NonNegativeFloat, NonNegativeFloat, NonNegativeFloat]) β [units = um]. Size in x, y, and z directions.
source_time (Union[GaussianPulse, ContinuousWave, CustomSourceTime]) β Specification of the source time-dependence.
direction (Literal['+', '-']) β Specifies propagation in the positive or negative direction of the injection axis.
angle_theta (float = 0.0) β [units = rad]. Polar angle of the propagation axis from the injection axis.
angle_phi (float = 0.0) β [units = rad]. Azimuth angle of the propagation axis in the plane orthogonal to the injection axis.
pol_angle (float = 0) β [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, whilepol_angle=np.pi/2
specifies S polarization. At normal incidence when S and P are undefined,pol_angle=0
defines: -Ey
polarization for propagation alongx
.-Ex
polarization for propagation alongy
.-Ex
polarization for propagation alongz
.
Example
>>> pulse = GaussianPulse(freq0=200e12, fwidth=20e12) >>> pw_source = PlaneWave(size=(inf,0,inf), source_time=pulse, pol_angle=0.1, direction='+')
