Importing the package dependencies: numpy, PyMieSim

import numpy
from TypedUnit import ureg

from PyMieSim.experiment.detector import Photodiode
from PyMieSim.experiment.scatterer import Sphere
from PyMieSim.experiment.source import Gaussian
from PyMieSim.experiment import Setup
from PyMieSim.polarization import RightCircular

Defining the source to be employed.

source = Gaussian(
    wavelength=1200 * ureg.nanometer,
    polarization=RightCircular(),
    optical_power=1e-3 * ureg.watt,
    NA=0.2 * ureg.AU,
)

Defining the ranging parameters for the scatterer distribution

scatterer = Sphere(
    diameter=2000 * ureg.nanometer,
    property=Material.BK7,
    medium_property=1 * ureg.RIU,
    source=source,
)

Defining the detector to be employed.

detector = Photodiode(
    NA=[0.1] * ureg.AU,
    phi_offset=numpy.linspace(-180, 180, 20) * ureg.degree,
    cache_NA=0.05 * ureg.AU,
    gamma_offset=0 * ureg.degree,
    sampling=400 * ureg.AU,
    polarization_filter=None,
)

Defining the experiment setup

experiment = Setup(scatterer=scatterer, source=source, detector=detector)

Measuring the properties

dataframe = experiment.get("coupling")

Plotting the results

dataframe.plot(x="detector:phi_offset")
