Sources#

class PlaneWave#

Bases: BaseSource

Monochromatic plane wave source.

This source models a spatially uniform incident field with a specified wavelength, polarization, and electric field amplitude.

add_to_scene(self: PyMieSim.single.source.BaseSource, scene: object, **kwargs) → None#

property amplitude#

Electric field amplitude.

Returns:: Field amplitude with units of electric field (V/m).
Return type:: pint.Quantity

property polarization#

Convenience Jones vector.

Returns the first row of polarization_element as a vector [Ex, Ey].

Returns:: Complex array of shape (2,).
Return type:: numpy.ndarray

property wavelength#

Wavelength in vacuum.

Returns:: Wavelength with units of length.
Return type:: pint.Quantity

property wavenumber_vacuum#

Vacuum wavenumber.

This is defined as k0 = 2*pi / wavelength.

Returns:: Wavenumber with units of inverse length.
Return type:: pint.Quantity

class Gaussian#

Bases: BaseSource

Monochromatic Gaussian beam source.

This source models a diffraction limited Gaussian beam characterized by its wavelength, polarization, numerical aperture, and optical power.

Notes

The numerical_aperture is treated as dimensionless and is used to derive the beam waist and related quantities in the C++ implementation.
