Types of Sources#

`tidy3d.PointDipole`	Uniform current source with a zero size.
`tidy3d.UniformCurrentSource`	Source in a rectangular volume with uniform time dependence.
`tidy3d.PlaneWave`	Uniform current distribution on an infinite extent plane.
`tidy3d.ModeSource`	Injects current source to excite modal profile on finite extent plane.
`tidy3d.GaussianBeam`	Gaussian distribution on finite extent plane.
`tidy3d.AstigmaticGaussianBeam`	The simple astigmatic Gaussian distribution allows both an elliptical intensity profile and different waist locations for the two principal axes of the ellipse.
`tidy3d.CustomFieldSource`	Implements a source corresponding to an input dataset containing `E` and `H` fields, using the equivalence principle to define the actual injected currents.
`tidy3d.CustomCurrentSource`	Implements a source corresponding to an input dataset containing `E` and `H` fields.
`tidy3d.TFSF`	Total-field scattered-field (TFSF) source that can inject a plane wave in a finite region.

`tidy3d.GaussianPulse`	Source time dependence that describes a Gaussian pulse.
`tidy3d.ContinuousWave`	Source time dependence that ramps up to continuous oscillation and holds until end of simulation.
`tidy3d.CustomSourceTime`	Custom source time dependence consisting of a real or complex envelope modulated at a central frequency, as shown below.
