Visualizing fields

The setup facade exposes the existing plotting and representation helpers. First create a simulation, then request the representation that matches the question you want to investigate.

from PyMieSim import (
    Gaussian,
    PolarizationState,
    Simulation,
    Sphere,
    ureg,
)

simulation = Simulation(
    scatterer=Sphere(
        diameter=500 * ureg.nanometer,
        material=1.5,
        medium=1.0,
    ),
    source=Gaussian(
        wavelength=700 * ureg.nanometer,
        polarization=PolarizationState(angle=0 * ureg.degree),
        optical_power=1e-3 * ureg.watt,
        numerical_aperture=0.2,
    ),
)

simulation.plot_system()
farfields = simulation.get_representation("farfields")
farfields.plot()
