Far-Fields Computation and Visualization

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

Importing the package: PyMieSim

from PyMieSim.single.scatterer import Sphere
from PyMieSim.single.source import Gaussian

Defining the source

source = Gaussian(
    wavelength=0.5e-6,  # 1000 nm
    polarization_value='right',  # Right circular polarization
    polarization_type='circular',
    optical_power=1,  # Arbitrary units
    NA=0.3  # Numerical Aperture
)

Defining the scatterer

scatterer = Sphere(
    diameter=1.5e-6,  # 1500 nm
    source=source,
    index=1.4,  # Refractive index of the scatterer
    medium_index=1.0  # Refractive index of the surrounding medium
)

Computing the data

data = scatterer.get_far_field(sampling=100)  # Specify the number of sampling points

Plotting the data

figure = data.plot()

Display the plot

_ = figure.show()
