SPF Computation

This example demonstrates the computation and visualization of the Scattering Phase Function (SPF) using PyMieSim.

Importing the package: PyMieSim

from PyMieSim.units import ureg

from PyMieSim.single.scatterer import CoreShell
from PyMieSim.single.source import Gaussian
from PyMieSim.single.representations import SPF
from PyMieSim.single.polarization import RightCircular

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

scatterer = CoreShell(
    core_diameter=500 * ureg.nanometer,
    shell_thickness=400 * ureg.nanometer,
    source=source,
    core_refractive_index=1.4 * ureg.RIU,
    shell_refractive_index=1.8 * ureg.RIU,
    medium_refractive_index=1.0 * ureg.RIU,
)


spf = SPF(scatterer=scatterer, sampling=300)

figure = spf.plot()
