Far-Fields Computation and Visualization

This example demonstrates the process of computing and visualizing the far-fields of a scatterer using PyMieSim.

from PyMieSim.units import ureg
from PyMieSim.single.source import Gaussian
from PyMieSim.polarization import PolarizationState
from PyMieSim.single.scatterer import Sphere
from PyMieSim.single.setup import Setup
from PyMieSim.material import SellmeierMaterial

material = SellmeierMaterial("BK7")

polarization = PolarizationState(angle=30 * ureg.degree)

source = Gaussian(
    wavelength=1000 * ureg.nanometer,
    polarization=polarization,
    optical_power=1 * ureg.watt,
    numerical_aperture=0.3,
)

scatterer = Sphere(
    diameter=1500 * ureg.nanometer,
    material=material,
    medium=1.0,
)

setup = Setup(
    scatterer=scatterer,
    source=source,
)

far_fields = setup.get_representation("farfields", sampling=100)

figure = far_fields.plot()
