Using pip
pip install hyperbolic-optics
Using uv (recommended for modern Python development)
uv add hyperbolic-optics
Development Installation
For development or to get the latest features:
git clone https://github.com/MarkCunningham0410/hyperbolic_optics.git
cd hyperbolic_optics
pip install -e .
Quick Start
Here's a simple example to get you started:
import json
from hyperbolic_optics.structure import Structure
from hyperbolic_optics.mueller import Mueller
# Define a simple multilayer structure
payload = {
"ScenarioData": {
"type": "Simple",
"incidentAngle": 45.0, # degrees
"azimuthal_angle": 0.0, # degrees
"frequency": 1460.0 # cm^-1
},
"Layers": [
{
"type": "Ambient Incident Layer",
"permittivity": 50.0
},
{
"type": "Semi Infinite Anisotropic Layer",
"material": "Calcite",
"rotationX": 0,
"rotationY": 90,
"rotationZ": 0
}
]
}
# Create and execute the simulation
structure = Structure()
structure.execute(payload)
# Calculate reflectivities
R_pp = abs(structure.r_pp)**2
R_ss = abs(structure.r_ss)**2
print(f"p-polarized reflectivity: {R_pp}")
print(f"s-polarized reflectivity: {R_ss}")
# Perform Mueller matrix analysis
mueller = Mueller(structure)
mueller.set_incident_polarization('linear', angle=45)
mueller.add_optical_component('anisotropic_sample')
# Get Stokes parameters and polarization properties
all_params = mueller.get_all_parameters()
print(f"Reflectance (S0): {all_params['S0']}")
print(f"Degree of polarization: {all_params['DOP']}")

Advanced Features
Custom Materials
Define materials with arbitrary permittivity and permeability tensors:
custom_material = {
"eps_xx": {"real": 2.27, "imag": 0.001},
"eps_yy": {"real": -4.84, "imag": 0.755},
"eps_zz": {"real": -4.84, "imag": 0.755},
"eps_xy": {"real": 0.0, "imag": 0.0},
"eps_xz": {"real": 0.0, "imag": 0.0},
"eps_yz": {"real": 0.0, "imag": 0.0},
}
Multiple Scenario Types
- Incident: Frequency vs incident angle analysis
- Azimuthal: Frequency vs azimuthal rotation analysis
- Dispersion: k-space dispersion at fixed frequency
- Simple: Single-point calculation for specific conditions
Built-in Visualization
from hyperbolic_optics.plots import plot_mueller_dispersion, plot_kx_frequency
# Generate publication-quality plots
plot_kx_frequency(structure, reflectivity, save_name="my_plot")
